Gold doesn't support 16-bit real mode code, which is what a BIOS is, so until it does its can't be considered a full replacement to ld.bfd.
Until gold supports 16-bit real mode there's nothing for the virtualization guys to do here. You're building a BIOS, there's no other options other than what we need. Given that gold creates Grub's that aren't bootable, that should have been the first warning this wouldn't work. Kicking this over to toolchain to see how they want to triage this.
you could file a bug upstream, but i suspect they aren't interested in supporting it in gold ... if the -fuse-ld flag ever goes mainline, we'll probably want to update packages to start using that.

afaik gold doesn't plan on supporting this, and all the known packages that need it use the bfd-fallback helpers. if you find packages that still fail, please file new bugs for each one.
