I thought not, but it appears it would match all of powerpc*

(ins)scheme@(guile-user)> (use-modules (ice-9 regex))
(ins)scheme@(guile-user)> (string-match "powerpc" "powerpc")
$1 = #("powerpc" (0 . 7))
(ins)scheme@(guile-user)> (string-match "powerpc" "powerpc64le")
$2 = #("powerpc64le" (0 . 7))
(ins)scheme@(guile-user)> (string-match "powerpc" "armhf")
$3 = #f

If it were string=? then it would be fine, but that would break the
^i[3456]86$ regex. It looks like I would need to add a powerpc64 case
above the powerpc case. Looking at the output of qemu adding
((string-match "powerpc64" cpu) "ppc64") would be the right answer.
