I just checked, and for the record the second rule (ifneq
($(abs_top_builddir),) is actually preventing it. On top of
Makefile.global:

# Set top_srcdir, srcdir, and VPATH.
ifdef PGXS
top_srcdir = $(top_builddir)
[...]
else # not PGXS
[...]
abs_top_builddir = @abs_top_builddir@
[...]
endif # not PGXS

It makes sense. Thanks for correcting and pushing!
