svn commit: r316101 - head/lib/libgcc_s

[Ngie Cooper]

Author: ngie
Date: Tue Mar 28 19:01:01 2017
New Revision: 316101
URL: https://svnweb.freebsd.org/changeset/base/316101

Log:
  Apply r315689 to lib/libgcc_s as well to unbreak the gcc xtoolchain build
  
  lib/libgcc_s consumes lib/libcompiler_rt/Makefile*. The NO_WERROR.gcc in
  lib/libcompiler_rt/Makefile doesn't seem to have made a difference in being
  able to build this, so sprinkle NO_WERROR.gcc here as well.
