Subject: [PATCH] Add additional CI pipelines

- Gentoo Linux GCC and Clang (via gentoo/stage3:nomultilib)
- GCC LTO (via fvwmorg/fvwm3-build)

While the issue with LTO builds has been resolved in this PR, it was
incidental and we should introduce a CI pipeline that will catch
LTO errors before they make it into a release.

Closes: https://github.com/fvwmorg/fvwm3/issues/1056
