CircleCI: add large ressource class for free tier as defined under ht…

Readd linuxboot#984 without cache
Change CPUS=16 to -j16 in CircleCI config
Add kgpe-d16 musl-cross target prior of having kgpe-d16 depend on musl-cross target (To try to have musl-cross step successfull under 1h CircleCI new limit)
CircleCI: add a subcommand that can follow a target (to build musl-cross-make now and coreboot version specific musl-cross later)
Output of hashes is now optional
