With this little additional patch, you can now run "make check" in PGXS-using extensions (instead of having to do make install; make installcheck with a running instance). I think this would be very convenient for extension development.

Might make sense to use `dirname` on all the entires in DATA and MODULES to figure out what to put in the search paths. I usually have my C files in `src` and SQL files in `sql`, and wrote the PGXN tutorial[1] back in 2012 with that pattern (for better or worse). A simple example is the envvar extension[2]:

Interesting. I think to support that, we would need to do a temp
install kind of thing of the extension, and then point the path settings
into that temp install directory. Which is probably more sensible anyway.
