Changed by q66: we're now using an upstream snapshot from alpine; this should allow us to get an assortment of regression fixes without having to patch them in also libssp fixes for musl, and typo fixes for libstdc++-devel pkg function also drop gccgo on 32-bit powerpc Co-authored-by: q66 <daniel@octaforge.org>
