Change subject: util/abuild: Clean up the missing_arches check
......................................................................

Patch Set 4:

With this patch abuild always fails for me with

/tmp/GmkR0sEo:1: .xcompile: No such file or directory
 make: *** No rule to make target '.xcompile'.  Stop.
 Calculating missing_arches failed

Was that intended? I normally only use abuild to test builds and never run 'make' directly in my coreboot checkout, so I don't have an .xcompile in there. Normally abuild just generates its own .xcompile in coreboot-builds/<board>/xcompile.build and uses that. Can't we make whatever this was trying to do do it that way too? I'd like abuild to work on its own in a clean checkout.
