clang ignores the -fno-inline-functions-called-once option, but warns
when building with -Wignored-optimization-argument enabled:
clang: error: optimization flag '-fno-inline-functions-called-once' is not supported [-Werror,-Wignored-optimization-argument]
Move it back to using cc-option for this one.
Fixes: 7d73c3e9c514 ("Makefile: remove stale cc-option checks")
