OK. I've reduce that to the attached (WIP) patch .
Problem is usage of $(srcdir) in the PGXS case. I try to remove it in favor of
recipes for each case (DATA, DOCS, ...)

It's a quick hack... It does not handle some cases yet (for example it does
not find .o when come the time to build .so if the .o was already in VPATH),
this later issue is a separate one I think.

If it seems to be on the right way, I'll keep fixing EXTENSION building with
VPATH.
