Yes, I fuxed it in g:77eccbf39ed.  That needed the g:80fcc4b6afee fixup, and
will need more work in the future. but this PR is fixed indeed :-)

This seems to have been fixed meanwhile. My Gentoo ppc/ppc64 box says:

 # gcc-9.5.0 -S -m32 -mcpu=7450 -frecord-gcc-switches -xc -o - - < /dev/null |
grep -E 'mcpu|machine'
.ascii  "-mcpu=7450"

 # gcc-10.4.0 -S -m32 -mcpu=7450 -frecord-gcc-switches -xc -o - - < /dev/null |
grep -E 'mcpu|machine'
.machine "7450"
.ascii  "-mcpu=7450"

 # gcc-11.3.0 -S -m32 -mcpu=7450 -frecord-gcc-switches -xc -o - - < /dev/null |
grep -E 'mcpu|machine'
.machine power7
.string "GNU C17 11.3.0 -msecure-plt -m32 -mcpu=7450"

 # gcc-12.1.1 -S -m32 -mcpu=7450 -frecord-gcc-switches -xc -o - - < /dev/null |
grep -E 'mcpu|machine'
.machine "7450"
.string "GNU C17 12.1.1 20220625 -msecure-plt -m32 -mcpu=7450"

This would be on the 32bit chroot of my Talos II.

Perhaps we should just ignore AltiVec for the .machine selection?
