Subject: arm: Only support ARM64_CRC32 when using GCC
X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=c2e5eea38a25c3b787bb243f7d9638cd6e634cd4;p=u-boot.git

arm: Only support ARM64_CRC32 when using GCC

Today, only gcc has __builtin_aarch64_crc32b (clang-16 does not, for
example). Make this option depend on CC_IS_GCC.
