Then let's rediscuss making ARM a primary architecture when that happens.
Right now the speed is just not acceptable.

That alone means it's not a solution.
Also note that not everything in builds is parallelizable:
* not all upstream build systems use make -j,
* configure (or cmake etc.) and make install are usually not parallelized,
* often there are makefile dependencies requiring at least some amount of
serialization
etc. So even if you have -j working, you STILL need a comparable speed in
ONE core compared to the x86 builders.
