That was my first idea, too, so I tried that, to no avail.  The check
that fails is the one that tries to determine the name of the default
output file (like a.out), and obviously, things like CFLAGS are being
completely ignored there.

After digging through many an m4 file around, I eventually stumbled
across AC_NO_EXECUTABLES which apparently seems to do exactly what I
want -- and is, of course, completely undocumented in the regular docs
(i.e. the info files). :-((

It's all in avr-libc's CVS if anybody wants to play with it.  You can
check out it online.

1.9/2.59

Note that avr-gcc is not the problem here, only avr-libc's new auto*
setup.

FreeBSD ;-)
