Per the release notes for 1.5.0, the CMake build is preferred going
forward. This lets us drop some Makefile patches and pass them as CMake
options instead, with the exception of disabling mold-wrapper.so.
The port exposes some dynamic loader and toolchain shortcomings,
namely RTLD_NEXT, RTLD_NOLOAD, and std::filesystem. Hopefully we can
discover a ton of multi-threading bugs in Serenity with this port :^)
