I think I will work on GRUB on SPARC next to address the build issues there.
Before re-enabling COFF for GRUB, we could look into GRUB as ELF on sparc64,
because looking at OpenBSD, their second stage bootloader is actually an ELF
binary:
```
root@nfs:/srv/nfs/openbsd/6.3/sparc64# file ofwboot.net
ofwboot.net: ELF 64-bit MSB executable, SPARC V9, relaxed memory ordering,
version 1 (SYSV), statically linked, stripped
root@nfs:/srv/nfs/openbsd/6.3/sparc64# file bsd.mp
bsd.mp: ELF 64-bit MSB executable, SPARC V9, total store ordering, version 1
(SYSV), statically linked, not stripped
```
...so the sparc64 firmware seems to also support ELF binaries. And according to
[6] this seems to work for a lot of systems. If an ELF version of GRUB can be
provided by someone, I have a lot of sparc64 gear to test on - though not as
many as OpenBSD supports ;-).
I do actually. I have built a version of GRUB for sparc64 with the COFF
linker options stripped off. Feel free to try the packages from [1].
If we actually don't ned COFF even on older SPARC boxes, that would be
great.

Cool, thanks, will give that a try on my current local machines for a
start and report back.
Cheers,
