I think that pretty much nails it down.

This for instance makes it impossible (on Linux) to make test
from a source/build directory with RPATH without doing
"make install" first.

Why not simple give it the absolute LIBDIR path from configure?

By the way, as already stated in another mail:
You can link your binaries with any RPATH you like by calling
configure this way (without modifications to samba code):

LDFLAGS="-R..." ./configure --prefix=... ...
