[PATCH 5/6] x86/build: Remove cc-option from -mskip-rax-setup

[Nathan Chancellor]

This has been supported in GCC since 5.1 and clang since 14.0. Now that
x86 requires LLVM 15 or newer since commit 7861640aac52 ("x86/build:
Raise the minimum LLVM version to 15.0.0"), this flag can be
unconditionally added, saving a compiler invocation.
