fails
------------------------+---------------------
 Reporter:  ryandesign  |      Owner:  (none)
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.7.2
 Keywords:  elcapitan   |       Port:  llvm-15
------------------------+---------------------
 clang-15 builds for multiple archs (i386 and x86_64 and even x86_64h!)
 even without the universal variant being selected which fails on OS X
 10.11 when it tries to link with the legacy support library which has been
 built only for x86_64.
