Worked around in https://svnweb.freebsd.org/changeset/ports/512594
If you don't want to install more than one devel/llvm* define
DEFAULT_VERSIONS+=3Dllvm=3D80 in make.conf(5).

Alternatively, help fixing lang/clover to work with llvm90. Mesa ports
are unlikely to be updated until Summer next year due to low demand.
