A few differences with the original link targets: - 'libs' is now supported on all arch even though only x86 uses it - compiler_rt is included on arch that previously did not (arm). This however has no impact as there compiler_rt is not defined for those arch in xcompile - LIBGCC_FILE_NAME_bootblock is not included, but this was not defined anywhere so this is a noop Change-Id: I64f7686894c99732d06972e7ba327061db6d7c44 Signed-off-by: Arthur Heymans <arthur@aheymans.xyz> Reviewed-on: https://review.coreboot.org/c/coreboot/+/83574 Reviewed-by: Nico Huber <nico.h@gmx.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
