build: Convert warnings into errors when testing for -fstack-clash-protection
When building with Clang, if `-fstack-clash-protection` is used with an
unsupported target, it may result in hundreds of
`-Wunused-command-line-argument` warnings at compile time. This is
currently the case when building for at least Darwin using Apple or LLVM
Clang.
Unsupported targets may also include *BSD, however that is changing; see
further discussion in https://reviews.llvm.org/D92245 and
https://reviews.freebsd.org/D27366.
Note that this option is already skipped for Windows.
