Running Python from the build directory can lead to wrong `libpython` being loaded

Feature or enhancement

Proposal:

Right now, since we don't set RPATH, when using a shared libpython and running Python from the build directory, the library might resolve to the system, instead of the local one.

If possible, it would be good to set RPATH on the Python binary in the build directory, to force the local libpython library to be loaded. It would also be preferred to use RPATH instead of RUNPATH, as the prior has precedence over LD_LIBRARY_PATH, which users might have set.

Has this already been discussed elsewhere?
