I donât think the assembly stage needs to be done locally. gcc can still be
used to deploy the assembler. I am not too familiar with distcc, so I donât
know whether the preprocessing supports multiple source-files, and whether
it has some strange-behavior when it comes to .S/.s files.

Well, Iâll give it a try.
