Hmmm, I learn something every day :) However, man mktemp says -t is
deprecated.

But mktemp -p /tmp "$me-XXXXXXXX" would work equally well.

Sure, that's a bit nicer.

Sure, although the tests will get re-run every time you type "make" that
way, which might annoy some people.

I am looking into generating some more useful predefines for the information
suppiled by __ARM_ARCH_* --- this is more cumbersome though and really needs
to be a separate script, but it has potential to simplify all the #if
defined(this) || defined(that) || defined(the other) || ... and reduce the
maintenance effort.

Sure. I'm still too scared of autoconf to set it up from scratch though :O
