x86/build: Remove cc-option from -mskip-rax-setup

This has been supported in GCC since 5.1 and clang since 14.0. Now that x86
requires LLVM 15 or newer since

  7861640aac52 ("x86/build: Raise the minimum LLVM version to 15.0.0"),

this flag can be unconditionally added, saving a compiler invocation.
