Use C locale when setting CC_VERSION_STRING and LD_VERSION_STRING.

The output reported may be locale-dependent, which results in unreproducible builds. $ LANG=C ld --version | head -n 1 GNU ld (GNU Binutils for Debian) 2.26 $ LANG=it_CH.UTF-8 ld --version | head -n 1 ld di GNU (GNU Binutils for Debian) 2.26 Forcing LC_ALL=C ensures the output is consistant regardless of the build environment. Thanks to HW42 for debugging the issue: https://lists.alioth.debian.org/pipermail/reproducible-builds/Week-of-Mon-20160606/005722.html For more information about reproducible builds: https://reproducible-builds.org/ Signed-off-by: Vagrant Cascadian <[email protected]> Reviewed-by: Tom Rini <[email protected]>

 # The SOURCE_DATE_EPOCH mechanism requires a date that behaves like GNU date.
