linux: generate KBUILD_BUILD_TIMESTAMP date whith LC_ALL=C
Fix kernel reproducible build if a non-C locale is used on the host
system.
When building the Linux kernel, scripts/gen_initramfs_list.sh does 'date
-d"$KBUILD_BUILD_TIMESTAMP" +%s'. In linux.mk, Buildroot sets
KBUILD_BUILD_TIMESTAMP to "$(shell date -d @$(SOURCE_DATE_EPOCH))".
For example, if LANG=fr_FR.UTF-8 is defined in the host system, it does
not work:
- LC_ALL=C date -d"$(LC_ALL=C date)" : ok
- LC_ALL=C date -d"$(LC_ALL=fr_FR.UTF-8 date)" : error
LANG/LC_ALL variables exported in the main Makefiles are not passed in
the $(shell ...) sub-shells.
