The trick is to override this bit in

PG_CONFIG = pg_config

bindir := $(shell $(PG_CONFIG) --bindir)
datadir := $(shell $(PG_CONFIG) --sharedir)
... etc ...

It might be better if the standard invocation of a PGXS build were not

ifdef USE_PGXS
PGXS := $(shell pg_config --pgxs)
include $(PGXS)

but something like

ifdef USE_PGXS
PG_CONFIG := pg_config
PGXS := $(shell $(PG_CONFIG) --pgxs)
include $(PGXS)

to sync these invocations of pg_config with the ones in  I'm not sure though how to get this setting to
override the one in ... or should we just remove
that one?
