This is incomplete. I guess it can be committed as is, but should be
followed by re-addition of:
bfin-*-*)
noconfigdirs="$noconfigdirs target-boehm-gc"
;;
cris-*-* | crisv32-*-*)
case "${target}" in
*-*-linux*)
;;
*) # See PR46792 regarding target-libffi.
noconfigdirs="$noconfigdirs target-boehm-gc";;
esac
;;
mmix-*-*)
noconfigdirs="$noconfigdirs target-boehm-gc"
;;
(perhaps in the same case as target-libffi handling).
