True. How about rather than -F CFLAGS=... accepting all the -m options like -mpcu=... -mabi= -marm -mtune= and passing them to the appropriate CFLAGS/AFLAGS/LDFLAGS (most can just go to all three). > I'm not sure if there's a good answer for what an "ambiguous" compiler > should produce with buildrump.sh.

Thats an odd situation, is that the NetBSD compiler on pi or the Linux one? It is not clear that buildrump can work out all the unsupported situations.
