Subject: [PATCH] Makefile: Conditional assignment of python exe

Using `:=` while providing an override (either in Makefile.conf or on the command line) does not correctly apply the override in other simply expanded variables (using `:=`).  Instead, passing an explicit `PYTHON_EXECUTABLE=python3.15` while leaving `PYTHON_CONFIG` implicitly defined results in it being set to `python3-config` instead of the expected `python3.15-config`.
