toolchain-external: add a check for unsupported toolchains
Some toolchain can't be used by Buildroot due to sysroot location
issue, so the $(ARCH)-linux-gnu-gcc -print-file-name=libc.a command
return only "libc.a"
This lead to an error during the header check version helper,
so these toolchains can't be imported into Buildroot.
cc1: fatal error: $PWD/libc.a/usr/include/linux/version.h: No such file or directory
compilation terminated.
support/scripts/check-kernel-headers.sh: line 38: /tmp/check-headers.4V5PPF: Permission denied
This issue happen with the first linaro 2015.11 [1] release and
CodeSourcery standard edition [2].
Here is the sysroot directory tree for linaro 2015.11:
$ ls libc/arm-linux-gnueabihf
etc lib sbin usr var
Here is the sysroot directory tree for CodeSourcery standard:
$ ls libc/sgxx-glibc
etc lib lib64 sbin usr var
Add a check to error out with an explicit error message
The check don't use toolchain_find_libc_a function directly since
"realpath -f" is used internally and return an absolute path.
