Right now `libomp.so` isn't versioned, meaning only a single version can be installed at the same time
(at least that is what i see in debian). So API/ABI break as such will mean that if `libomp.so`
from git master is installed, clang-9-based openmp will no longer be usable, only clang from git master.
That's kinda not great to put it mildly.
