pnr/openroad: add osx build

[xobs]

This simple patch gets openroad building on arm64:

Note that there is a separate entry under run for spdlog. Before that line was added, the package built with spdlog 1.9.2 but installed with 1.11.0, which is incompatible.

The relevant issue on spdlog: https://github.com/The-OpenROAD-Project/OpenROAD/issues/2220

@xobs do you want to add a job for -osx similar to https://github.com/hdl/conda-eda/blob/master/.github/workflows/Build.yml#L371-L379 ?

[xobs]

Sure. I'm guessing these runners don't actually have the ability to execute software, which is why things with tests have --no-test? Should I also skip tests on openroad?

I think they do, but they would build the x64 version (not arm64).

[xobs]

Alright, I think that adds a Build step that works.

Some build error on macosx x64:

https://conda-forge.org/docs/maintainer/knowledge_base.html#newer-c-features-with-old-sdk seems to imply that this is safe to disable with CXXFLAGS="${CXXFLAGS} -D_LIBCPP_DISABLE_AVAILABILITY" but I wonder if it also apply to non-conda forge c++ toolchain (I guess yes, since it mentions that url in the error message).

for the record github runner environment include the following MacOSX SDKs: https://github.com/actions/runner-images/blob/main/images/macos/macos-12-Readme.md#installed-sdks

[xobs]

@proppy I believe I added D_LIBCPP_DISABLE_AVAILABILITY to the build. Would you mind trying the build again?

[xobs]

Looks like openroad-osx built this time
