Author: dim

New Revision: 242553
URL: http://svn.freebsd.org/changeset/base/242553

Log:
  MFC r238864:
  
  Similar to what is already done for Linux, make clang not complain about
  unused -g, -emit-llvm or -w arguments when doing linking.  E.g. invoking
  "clang -g foo.o -o foo" will now be silent.
