"mostly used" is probably an overstatement. There are probably more ARM
toolchains out there than linux distros (which were our main concern
with requiring buildgcc toolchains, given how they all managed to mess
up gcc for us). I expect the same kind of trouble with all these, so
we'd better have some standard toolchain around that we can point people to.

In that case if/when people chose to use their own toolchains and things
break, that's their problem, not ours.

That script was originally created for building ARM toolchains, before
we repurposed it for coreboot uses (because of the toolchain mess hinted
at above).

It should be enough to run "buildgcc -p arm-elf" (or arm-none-eabi or
something), with maybe a bugfix here or there.
