svn commit: r364122 - head/share/mk

New Revision: 364122
URL: https://svnweb.freebsd.org/changeset/base/364122

Log:
  Add CLANG/LLD/LLD to BROKEN_OPTIONS when building on non-FreeBSD
  
  These tools require a bootstrap llvm-tblgen/clang-tblgen and that cannot
  be built with the current make infrastructure: the config header is not
  correct for Linux/macOS and we don't include the CMakeLists.txt in contrib
  so we can't generate one that would be correct.
