Research direction
Start by tracing how the top-level make -j14 crossgcc-i386 iasl invokes make -C util/crossgcc build-i386 build_iasl SKIP_GDB=1. Check whether the job limit reaches the toolchain build, then verify that building GCC uses multiple CPUs rather than one.

Description
"threads" is 14 on my machine, but the toolchain make that coreboot performs seems to be single-threaded. this might be a coreboot problem.
i can see the original make was called correctly from ps:
brho 253888 253487 0 14:54 pts/10 00:00:00 make -j14 crossgcc-i386 iasl
but i don't know if that's getting passed down correctly. here's the child:
`brho 253962 253888 0 14:54 pts/10 00:00:00 make -C util/crossgcc build-i386 build_iasl SKIP_GDB=1'
either way, it's been building GCC v8.1.0 for a long time now, and it's using at most one CPU.
