Also disable full bootstrapping. Since we always bootstrap from $pkgver minus one
we don't need it and it increases buildtime considerably.

Also keep in mind that we have to add new arches in multiple steps:
    1. Compile with the upstream triplets, compiling alpine's triplets in
    2. Compile again, now with our triplets selected as build/target, now that
       rustc knows about them

This means that the produced compilers MUST ONLY be used to bootstrap the actual
compilers with our triplets, DO NOT use these to compile packages! Since x86_64
still uses the usual triplets it's fine to upgrade/add packages for that arch
though, please DO NOT do this for armhf,armv7,aarch64,ppc64le or x86 though!

* Add patch to fix compatibility with python 3.7.

* Switch source to github and run provided test suite.

- build with MinSizeRel and -g1 to reduce memory usage during compile
- simplify cmake opts. default seems to do the right thing nowdays
- use nijna
- remove patch that apparetnly is not needed anymore
