My build issue is because of some tweaking I have to do in order to
be able to run the tools from the build directory (it's quite sad that
this still isn't supported "out of the box").

Indeed (except the first "local" you show wrongly isn't there), just
that there's some /home/jbeulich/.../ infix, but _no_ such prefix
(DESTDIR for the reason mentioned above can't be set to
/home/jbeulich/..., or [I don't recall] either the build breaks or
things don't work in the end, but needs to be forced to / on the
make command line; as said I have a compensating tweak
elsewhere so that the full resulting path is correct everywhere
_except_ now for DEBG_DIR).

That's a possible route; whether to keep two different things
named identically is another question.
