It was removed as a part of following commit
2009-06-10 Pavel Roskin <pro...@gnu.org>
* configure.ac: Use -nostdlib when probing for the target. It
should not be required to have libc for the target.
* configure.ac: Remove checks for __bswapsi2 and __bswapdi2,
they fail without libc headers for the target.
* include/grub/powerpc/libgcc.h: Use weak attribute for all
exports.
* include/grub/sparc64/libgcc.h: Likewise. Don't use
preprocessor conditionals.
Do you think we should just revert it?
