Hi hackers,

I noticed to my annoyance that 'make -j4 -C src/interfaces/libpq'
doesn't work in a clean checkout, because it can't find
libpgcommon_shlib and libpgport_shlib.  It looks like that's because the
submake-libpgport dependency is declared on the all-lib target, not on
the shlib itself.  Moving it to SHLIB_PREREQS instead fixes it, patch
for which is attached.

  the mainstream press' sense at least.               - Matt McLeod
- That'd be because the content of a tweet is easier to condense down
  to a mainstream media article.                      - Calle Dybedahl
