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).
