Subject: loongarch64: disable simd when build efi
X-Git-Tag: v256-rc1~610
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ff37c9fcbe1d88a3ea0c6174ba8424e3ea14a82b;p=thirdparty%2Fsystemd.git

loongarch64: disable simd when build efi

LoongArch does not yet support the `-mgeneral-regs-only` option, so when
compiling for EFI, we need to use the `-mno-lsx` and `-mno-lasx` options
to disable SIMD instructions.
