Thread: pgsql: Unlink static libraries before rebuilding them.

Unlink static libraries before rebuilding them.

When the library already exists in the build directory, "ar" preserves
members not named on its command line.  This mattered when, for example,
a "configure" rerun dropped a file from $(LIBOBJS).  libpgport carried
the obsolete member until "make clean".  Back-patch to 9.0 (all
supported versions).
