Comment (by kencu):

 the gcc10-bootstrap port is as close to a real cross compiler as we have
 for this, but still has a number of faults, and is not really a cross-

 It should be able to build a universal binary arm64-x86/64 if running on
 an M1 system, though, using rosetta.

 It lacks several important features, primary amongst them is a distinct
 universal driver ("driverdriver.c") and the different archs it can build
 currently have to run in the actual arch it is building for, so not
 exactly a cross-compiler, but again, on an M1, should probably work using

 With some minor tweaking it could become a cross compiler (where the
 compilers  run in the machine's host arch rather than the target arch) but
 that would need more work.
