The above makes poudriere builds of devel/llvm90 not depend
on libz3.so and does not try to build math/z3 or to put it
in place during the llvm90 build. But it would apparently
not help portmaster or the like avoid creating the dependency
if libz3.so was in place.
So poudriere users appear to have a way around the math/z3
consequences for now.
One of the consequences was the messages about:
OMP: Info #270: omp_set_nested routine deprecated, please use =
omp_set_max_active_levels instead.
Those are also gone by building and installing via
poudriere with such a devel/llvm90/Makefile .
It looks like portmaster or such needs to be used to see if
one has successfully disabled automatic libz3.so detection
in llvm90's cmake infrastructure. (I normally build via
poudriere-devel .)
