These patches have affected pgxs-using extensions that have their own 
TAP tests.

The portlock directory is created at

     my $build_dir = $ENV{top_builddir}
       || $PostgreSQL::Test::Utils::tmp_check ;
     $portdir ||= "$build_dir/portlock";

but for a pgxs user, top_builddir points into the installation tree, 
specifically at $prefix/lib/pgxs/.

So when running "make installcheck" for an extension, we either won't 
have write access to that directory, or if we do, then it's still not 
good to write into the installation tree during a test suite.

A possible fix is

diff --git a/src/Makefile.global.in b/src/Makefile.global.in
index 5dacc4d838..c493d1a60c 100644
