New Revision: 518116
URL: https://svnweb.freebsd.org/changeset/ports/518116

Log:
  Use clang 7 as compiler on 11.x and 12.x to fix build.
  
  clang 8 and later error for duplicate definitions of enum values.  mdb
  depends on having identical but duplicate definitions.  This was fixed
  differently in 13 with a change to the kernel, but that change is
  disruptive and cannot be easily backported.
