macOS 10.15 introduced full `std::filesystem::path` support. Before that our use of it would cause the build to fail. This was not caught because "-mmacosx-version-min=10.9" was only being passed to clang++ for release builds. This passes that flag in a new static CI test build, and introduces a hack developed by @LIJI32 to silence the availability errors, since we use features already available in macOS 10.9. This means we are testing both "vanilla" building, and building static binaries using the same configuration as during release, which should help avoiding last-minute surprises.

/**
|
|
* This is a hack to make RGBDS build on macOS 10.14 and below. Without it, we get errors like:
|
|
* error: 'path' is unavailable: introduced in macOS 10.15
|
|
* The hack weakens the `std::filesystem::path` availability error into a warning, by removing
|
|
* `strict` from the availability macros (for information on the `availability` attribute, see
|
|
* https://releases.llvm.org/17.0.1/tools/clang/docs/AttributeReference.html#availability). This is
|
|
* acceptable because what we need of `std::filesystem::path` was already supported in macOS 10.14
|
|
* (the last version to support 32-bit, hence in demand despite being superseded by 10.15 in 2019).
