Comment:
Successfully built all cross compilers for the 4 native architectures.
Noticed there are quite a few more now: all the 32 bit host to 64 bit target compilers.
Still uploading to https://misc.voidlinux.de/binpkgs but already using them to cross compile further packages.
So far looking good. The problems observed have reasons other than the cross compilers.
Most problems are due to missing aclocal-1.16 when packages need to regenerate files because of touched Makefile{,.in,.am} or other parts of the autoconf cruft; issues with wxWidgets and including wx/setup.h; or simply broken / non cross compiling packages.

BTW: I think the `gir` and/or `qemu` build helpers should detect `ppcle{,-musl}` and error out early because there is no `qemu-ppcle-static` and the `XBPS_TARGET_QEMU_MACHINE="ppc"` in the `ppcle.sh` cross profile is wrong anyway. This leads to (big) packages being built only to eventually fail after linking when trying to generate the introspection files with non-executable binaries. This unnecessarily slows down the try to build as much as possible for ppcle.
