A few cleanups

[neuschaefer]

Hi,

while trying to build maciNTosh in GitHub Actions CI, I ended up fixing a few things. Please take what you like :)

I'm not sure if I want to have github ci present in this repo.

That said, the other commits look good, can you squash them?

I always find squashing to be a rather lossy deal because it breaks the connection between specific commit message and content, so I prefer not to. I'll remove the CI commit though, and see what I can squash without significant loss of information.

I'm also a bit unsure about the last two (Work around(?) LD error: PHDR segment not covered by LOAD segment and Ignore incompatible-type errors). They point to real problems with newer toolchains, but the solutions might be problematic.

EDIT: feel free to merge now

rebased, and removed questionable commits (-Wno-...) for now
