I can quickly summarise what is needed for the ROMs that I'm involved with:

- OpenBIOS is currently built using the builder docker image hosted at 
https://github.com/openbios/openbios/pkgs/container/openbios-builder which is based 
upon the kernel crosstool archives.

I initially tried using the QEMU docker cross-compilers, however whilst the builds 
work the binaries generated would crash early for PPC/SPARC64. I suspect it's likely 
because of specific patches applied by Debian or the options used for the build but 
didn't really dig into it further.

- qemu_vga.ndrv is a tricky one: it's actually built by Metrowerks CodeWarrior 
running in an OS 9 VM in QEMU!

There is a project called Retro68 (https://github.com/autc04/Retro68) which is a port 
of gcc for 68k/ppc Macs which could potentially be used, however it would need 
conversion of the driver from Metrowerks to gcc, and also likely require the use of 
Apple's MPW headers which were free to distribute but whose copyright status is 
currently undetermined.


ATB,
