x86/build: Remove cc-option from -mno-fp-ret-in-387
This has been supported in GCC for forever and clang gained support for it as
an alias of '-mno-x87' in LLVM 14. 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.
