The real good fix will be to use test -x IMHO.  This ought to work in
this case, right?

But I don't want $ac_test_x, this is too bad a change.  My goal is
test='missing test' or something like this for tests that don't
support -x.

Likewise for `which -a'.  This should release us from handling the
PATH separator.  This are details which would clobber Autoconf way too
much, we must put them in a lower layer.

OTOH, if we do this, we lose portability in M4sh, which would be very
bad :(
