If so, would some sort of checksum be able to distinguish meaningful changes? Would it be computationally worthwhile? More broadly, I've been surprised to see lots of files associated with foreign architechtures reported in self-hosting buildworld logs on the Pi2/3. Things with mips, ppc and i386 in the pathname. The log always reports building "cross tools" when it's compiling for itself, which puts an odd meaning on the term "cross". Are cross tools and object files for alien hardware really needed in such a case?
