I've removed a reference to "most personal computers" being singleprocessor
machines in multiple arches' config help, and also brought the arch/arm spacing
for "singleprocessor" (vs. "single processor" used there originally) in line
with other arches that had that text.

The diff is included below, and cleanly applies and builds on my system. I have
not tested on other systems yet since a documentation fix shouldn't fail to
build inconsistently, but if that's no excuse, I'll be happy to test further
when I can.
