Fedora Dockerfiles incompatible with building directly on aarch64/arm64 target

Hi there!

Using the Fedora Dockerfiles to build on aarch64/arm64 targets doesn't work, because they always want to install cross-compilation toolchains.

However, those require the container to run on an x86_64 machine, making it impossible to even install them on aarch64/arm64 targets.

All the best, Alex
