bbf22692c2wrt pclmul patch: GL_CRC_X86_64_PCLMUL in effect overrides the earlier configure check which sets USE_PCLMUL_CRC32, so -mno-pclmul leads to a build failure. Just use the coreutils config check result for now. Bug: https://debbugs.gnu.org/79491 Closes: https://bugs.gentoo.org/959467 Thanks-to: Ionen Wolkens <ionen@gentoo.org> Signed-off-by: Sam James <sam@gentoo.org>

GL_CRC_X86_64_PCLMUL in effect overrides the earlier configure check which
|
|
sets USE_PCLMUL_CRC32, so -mno-pclmul leads to a build failure. Just use

the coreutils config check result for now.

Thanks to Ionen Wolkens <ionen@gentoo.org> for the investigation and
|
|
workaround.
