Yeah.  I hadn't realized how much duplication of effort is happening
within ecpg.  This was a somewhat reasonable solution when it was
first invented for libpq only, but building snprintf.o four times
is pretty silly.

On reflection, let's just go with the solution of building libpgport_lib.a
with the right flags (fPIC + threading) and leave libpgport.a alone.
That way we don't need a debate about whether there's an efficiency
cost worth worrying about.
