Do not build the foreign arch libgcc. We are using the one provided by Alpine's binary repository instead, and when building it here and trying to use it, we actually run into a conflict. I tried setting BOOTSTRAP="nolibc" first since there is already logic to then disable libgcc in the APKBUILD. But that also disables g++ which we do want to build, so we can't use this. Fixes: issue 2168
