summary:

bpo-35257: fix broken BLDSHARED - needs LDFLAGS too (GH-11297)


`BLDSHARED` needs to have both `LDFLAGS` and `LDFLAGS_NODIST`, not just `LDFLAGS_NODIST`; `PY_CORE_LDFLAGS` provides both.  For example, as it stands now with just `LDFLAGS_NODIST`, macOS universal builds are broken as the necessary `-arch` flags are no longer passed to the standard library extension module link step from `setup.py` resulting in extension modules being single architecture only.

(cherry picked from commit 44a3ee07e30e18d83e2730c093d8b0e930f0a06c)
