The big problem is that none of these work! It's due to many ocurrences of
athlon_* and athlon-* in the bash and m4 scripts (overall in "case") and
{.c,.h}.

athlon | athlon_*) in a location

athlon | athlon-*) in another location (but why?)

Other problem is the ambiguity of "athlon-xp-pc-linux-gnu" that
could not match with the regular expression *-*-linux-*.
It's contrary to the unambiguity of "i686-pc-linux-gnu", 3 minus signs
versus 4 minus signs.
