As part of the timeline posted in https://lists.freebsd.org/pipermail/freebsd-arch/2019-August/019674.html we are turning off building non-clang architectures by default. To that end, unless MAKE_OBSOLETE_GCC is defined, only build clang architectures as part of universe/tinderbox.
A commit references this bug: Author: imp Date: Wed Oct 9 20:59:10 UTC 2019 New revision: 353367 URL: https://svnweb.freebsd.org/changeset/base/353367 Log: Don't compile old gcc 4.2.1 archs by default in universe/tinderbox. Only compile clang supporting architectures of amd64, arm, arm64, i386, and riscv as part of universe. Compile the other architectures if MAKE_OBSOLETE_GCC is defined. In all cases, explicit lists of architectures in TARGETS= on the command line override. For mips, powerpc and sparc64, do the same thing we do for risvc when MAKE_OBSOLETE_GCC isn't defined and short-circuit their universe build with an echo saying to install the xtoolchain port or pkg.

I think this can be closed now?
