Comment (by kencu):

 I just tried again, Mark, and once m4 is installed, it does not require
 being rebuilt as +universal:

 So I why it didn't work for you, but at least on an M1 mac, what I said is
 perfectly valid.

 My best guess is that you didn't clean m4 before trying to rebuild it, but
 that is speculation.

 now, assimp won't build universal for me because libffi won't build
 universal at present on an M1 system [ticket:62449] but that is a separate
 issue.
