Right, I will use RTE_DEVEL_BUILD

It seems both are working, I will convert to single dash.

Yes it is useful in dev environment, but can be risky or strange when
packaged for production environment.
Shouldn't we have a switch to avoid a development garbage in production?
I suggest to use RTE_DEVEL_BUILD.

Yes, this patch could remove
export LD_LIBRARY_PATH=$build/lib:$LD_LIBRARY_PATH
in scripts/test-null.sh.

Isn't it -rpath, with a single dash?

As it is a variable setting, it should be added before the rules,
just after LDLIBS settings.
