Since macOS 15 `ld -single_module` warns with a deprecation message,
which makes configure scripts believe the flag is unsupported. That
in turn triggers a code path where `archive_cmds` is set to
```
$CC -r -keep_private_externs -nostdlib ... -dynamiclib
```
instead of just
```
$CC -dynamiclib ...
```
This code path was meant to trigger only on ancient macOS <= 14.4 where
libtool had to add `-single_module`, which is the default since macos
14.4, and is now apparently deprecated because the flag is a no-op for
more than 15 years.
The wrong `archive_cmds` causes actual problems combined with a bug in
OpenMPI's compiler wrapper (`CC=mpicc`), which appends `-rpath` flags,
which cause an error when combined with the `-r` flag added by the
autotools.
Spack's compiler wrapper doesn't do this, but it's likely there are
other compiler wrappers out there that are not aware that `-r` and
`-rpath` cannot be combined.
The fix is to change defaults: `lt_cv_apple_cc_single_mod=yes`.
* BF+ENH: Add wxwidgets 3.2.6 and py-wxpython 4.2.2
Improves compat with newer Python (>3.9) and numpy.
Fix error during configure step (even on at least some older
versions) by including 'pkgconfig' as a build dep so gtk+ is found.
* BF: Make wxpython use spack built wxwidgets instead of rebuilding
* Update var/spack/repos/builtin/packages/py-wxpython/package.py
Avoid using too new version of py-setuptools as license file format is currently not compatible.

* for config: let `syaml_dict` inherit from `dict` instead of `OrderedDict`. `syaml_dict` now only exists as a mutable wrapper for yaml related metadata.
* for spec serialization / hashing: use `dict` directly
This is possible since we only support cpython 3.6+ in which dicts are ordered.
This improves performance of hash computation a bit. For a larger spec I'm getting 9.22ms instead of 11.9ms, so 22.5% reduction in runtime.
* OSError.errno apparently is int | None, but already part of __str__ anyway so drop
* fix disambiguate_spec_from_hashes
* List[Spec].sort() complains, ignore it
* fix typing of KnownCompiler, and use it in asp.py
