svn commit: r335770 - head

[Bryan Drewery]

Author: bdrewery

New Revision: 335770
URL: https://svnweb.freebsd.org/changeset/base/335770

Log:
  tinderbox: If the clang lookup fails fallback to the old default behavior.
  
  This fixes errors from the MK_CLANG_BOOTSTRAP/MK_LLD_BOOTSTRAP lookups
  to not force using XCC/XLD but to rather just build them as normal by
  allowing their own bootstrap logic to work.
