Indeed.
There were some kind of issue with VPATH so that it was scratched when
building under pgxs.
ifdef PGXS
# We assume that we are in src/makefiles/, so top is ...
top_builddir := $(dir $(PGXS))../..
include $(top_builddir)/src/Makefile.global
top_srcdir = $(top_builddir)
srcdir = .
VPATH =
endif
Maybe something clever could be done with relative VPATHs, or by trying to
translate prefixes? On the other hand, I'm not a VPATH fan;-)
