Log:
  clang: allow -fstack-clash-protection on FreeBSD
  
  -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.
