Can't build on 21.10

[jacobgkau]

When attempting to build firmware from scratch on Pop!_OS 21.10, coreboot/crossgcc fails at the following line:

Building GCC v8.3.0 for target ... failed. Check 'build-i386-elf-GCC/build.log'.

Here is the build.log file: build.log

I brought this up about a month ago and @crawfxrd mentioned that using update-alternatives to set gcc-9 and gcc++-9 as the defaults might get this working, although those packages aren't currently installed by default or by the deps.sh script. This issue is to track any work required to get the build.sh script working again on 21.10. Ideally, any setup required would be handled in deps.sh.

GCC 11 is now used for the coreboot toolchain.

What would be nice to have is to provide toolchain binaries.

I believe this was fixed by #260. I've been building and flashing on lemp10 with 21.10.

The toolchain binaries would be nice in the future, it takes a while to download/build them on a fresh system.
