clang: allow -fstack-clash-protection on FreeBSD

Browse Source 
-fstack-clash-protection was added in Clang commit e67cbac81211 but was
enabled only on Linux.  It should work fine on FreeBSD as well, so
enable it.

To be discussed and upstreamed with a test.  The OS test should probably
just be removed.
