clarify status of ARM and 32-bit architectures #94
Description
The README says ARM is unsupported and 32-bit untested. At least for Apple M series ARM this seems to be out of date. (It looks like Github's CI runners for MacOS are actually M1, so there is evidence in our own actions.)
Do other ARM systems support libquadmath?
Has anyone tried to run the tests on 32-bit systems recently (apparently Github doesn't provide these)?
