 Initial disclaimer: This might be better relayed upstream.

 The ${prefix}/lib/postgresqlXX/pgxs/src/Makefile.global which is included
 by the PGXS mechanism defines CFLAGS and LDFLAGS, thereby overriding
 user’s own choice.

 There are two things here:

 1. Transform CFLAGS = and LDFLAGS = into CFLAGS += and LDFLAGS += to avoid
 overriding;

 2. Strip -arch XXX flags of both lines, to avoid forcing universal builds
 of extensions (e.g. postgis).
