from older versions of FreeBSD, try WITHOUT_CLANG to bootstrap to the tip of
head, and then rebuild without this option. The bootstrap process from

/etc/src.conf now affects only builds of the FreeBSD src tree. In the
past, it affected all builds that used the bsd.*.mk files. The old
behavior was a bug, but people may have relied upon it. To get this
behavior back, you can .include /etc/src.conf from /etc/make.conf
(which is still global and isn't changed). This also changes the
behavior of incremental builds inside the tree of individual
directories. Set MAKESYSPATH to ".../share/mk" to do that.
Although this has survived make universe and some upgrade scenarios,
other upgrade scenarios may have broken.
