  compiler-rt: Allow build without __c11_atomic_fetch_nand

Don't build atomic fetch nand libcall functions when the required
compiler builtin isn't available. Without this compiler-rt can't be
built with LLVM 13 or earlier.

Not building the libcall functions isn't optimal, but aligns with the
usecase in FreeBSD where compiler-rt from LLVM 14 is built with an LLVM
13 clang and no LLVM 14 clang is built.
