Framework builds on macOS now fail with a bus error when trying to run the
newly built _bootstrap_python. A simplified example:

--enable-framework causes a number of changes in interpreter building and
initialization. Since, as it stands, _bootstrap_python executable isn't and
doesn't need to be built as a framework, there is probably some path confusion
in getpath.c or elsewhere.
Prior to these changes (at 3.11.0a2 at least), it was still possible to run a
framework build executable in the build directory through some careful use of
build variables in Makefile (like how "make test" works). Without delving
deeper into it at the moment, I'm not sure what to suggest. It may be simpler
to just do a clean separate non-framework build to provide _bootstrap_python.
And/or possibly re-allow the use of --with-build-python to specify a
user-supplied build python. I wonder if there are certain configurations on
other platforms where there might be similar problems with the current approach.
I'm marking this as a "release blocker" since it is preventing building the
usual python.org macOS binary installer for 3.11.0a3. Since it is still early
in the release cycle for 3.11, the release manager might reasonably decide to
not delay the release for a fix and thus skip having a macOS installer for a3.
