You mean that we need using crossgcc creates our own ARM-gcc cross toolchain? Why must we do this? Could we just trust the famous and mostly used toolchain like g++?
"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.
In this script, it says that it could not create an ARM toolchain. Should I fix it?
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.
