What will become llvmlite 0.48.0 has landed support for llvm/22. 
The below builds, packages and tests look reasonable (just a few
skipped ones).

Not sure what's up with the s/${MODPY_DISTV}/0+unknown/ change in the
PLIST and what fix that would need.

miasm looks in rather poor shape but it still builds and packages.
Tests hang.

For now I suggest we land a fixed version of this update, unhook llvm/20
from the tree and see if anyone steps up to fix miasm (or at least
complains). If not, we can also drop both, llvmlite and miasm as already
discussed.
