efivar only makes sense on platforms that support UEFI.
UEFI is only supported by some architectures at the moment, being mostly
employed on platforms such as x86, x86_64 and aarch64. Some other
platforms such as MIPS and PowerPC may have some unofficial UEFI
support. UEFI is also limited to little endian architectures.
efivar was being supported in Buildroot without architecture
restrictions so far, however this has led to the creation of a number of
hacks in the recipes, mostly for architectures that are not supported by
UEFI.
In order to avoid spending more time to debug these failures and
maintaining more hacks for unsupported architectures, efivar can be
restricted to that platforms where it makes sense and where it is more
likely to receive some testing and actual usage.
The existing hacks for the now unsupported architectures are removed,
and the dependency is propagated to efibootmgr as it depends on efivar.

uClibc support was recently added to efivar through a small
compatibility patch.
This commit updates a comment in the efivar recipe to reflect this, as
we no longer have glibc as the only supported C library.

efivar uses dlfcn.h which is not available in static builds
configuration. Also propagate dependency to efibootmgr. This commit
also does s/requires/needs/ in comment while at it.

Upstream has changed version numbering scheme since version 25, which
came after version 0.24.
The two patches that we had in package/efivar/ were backports and so can
be dropped with this bump.
This new version also fixes the build failure with gcc 6.x, so:

linux/nvme.h has been renamed to linux/nvme_ioctl.h since 4.4, and we
have a patch to handle that situation. However, some Sourcery CodeBench
toolchains use 4.4 kernel headers but don't have that header file
renamed, and that is causing build failures. So, prevent this package
to be built using those toolchains.

The efivar internal build system uses flags such as -std=gnu11 ,
-Wmaybe-uninitialized , -flto which are available in gcc >= 4.7 only.
These flags are passed both to target build and to build a host tool.
For the host part, this has been worked around by overriding
'gcc_flags', but doing that for the target would remove all flags that
upstream intended for the target build.
Buildroot doesn't support building gcc 4.6 in its own toolchain anymore
but it's possible to use an external toolchain with gcc 4.6 which would
be unable to build this package.
This patch adds a limitation on toolchains with target gcc >= 4.7 to
make sure that the flags are available in the chosen toolchain.

efivar for Nios II also has to be linked with shared libgcc to avoid an
error due to FDE encoding in static libgcc when linking libefiboot.so.

Following the removal of eglibc support, this commit replaces all
occurences of "(e)glibc" by just "glibc". Most of the occurences are in
package Config.in comments.
In addition, when the form "an (e)glibc ..." was used, it is replaced by
"a glibc ...".

The efivar build process starts by building one tool for the host,
which is needed for the rest of the build. This tool currently fails
to build with old gcc versions because the gcc.specs used by efivar
specifies -std=gnu11. To address this, this patch:
- passes 'gcc_flags=' to the host build, so that the custom gcc specs
are not passed. They are in practice not needed for the build of
the simple makeguids host utility.
- passes -std=gnu99 instead of -std=c99 in the build of host
makeguids, because the source code uses anonymous structs and
unions, which requires std=gnu99 and not just std=c99
In addition, the build by default assumes that the target toolchain is
LTO capable, and that therefore you can call gcc-ar, gcc-nm and
gcc-ranlib. This fails short when the target toolchain is for example
gcc 4.7. To address this, we explicitly specify AR, NM and RANLIB to
be used, but pass them as make options instead of in the environment,
in order to override the values specified in the package Makefile.

efivar contains tools and libraries to manipulate EFI variables.
This package has some restrictions to build. It needs uchar.h which
apparently does not come in uClibc, and it also needs
__bswap_constant_*() definitions which are only present in glibc.
So, this package was limited to build with glibc toolchains.
Although it probably makes sense mostly on x86, x86-64 and aarch64
architectures, there are no architecture specific limitations which
would prevent it to build for other architectures, so this restriction
was not imposed. This package has been build-tested additionaly on many
architectures which support glibc, such as mips, MicroBlaze, sparc64,
ppc64. There were some build flag issues found when building to some of
these some architectures, although the flags can be also added in the
general case, so they were added by default.
It has also been found that in some host systems it failed to build due
to not generating the .pc files. This has been tracked to the use of
make 3.81, so a patch was prepared for it and was submitted upstream.
There's also a dependency on the linux/nvme.h header, which is somewhat
conturbed, as it has appeared in user space linux headers 3.12 and in
4.4 it was renamed. This has been solved by restricting it to build with
linux headers >= 3.12 and a patch from upstream was picked which fixes
it for linux headers >= 4.4.
