[PATCH 2/2] MIPS: Loongson64: Wrap -mno-branch-likely with cc-option

From: Nathan Chancellor
Date: Thu Jan 20 2022 - 16:40:20 EST


This flag is not supported by clang, which results in a warning:

clang-14: warning: argument unused during compilation: '-mno-branch-likely' [-Wunused-command-line-argument]

This breaks cc-option, which adds -Werror to make this warning fatal and
catch flags that are not supported. Wrap the flag in cc-option so that
it does not cause cc-option to fail, which can cause randconfigs to be
really noisy.
