Thread: pgsql: Add comment for why we recompile pgport C files.

Log Message:
-----------
Add comment for why we recompile pgport C files.

# Need to recomple any libpgport object files because we need these
# object files to use the same compile flags as libpq.  If we used
# the object files from libpgport, this would not be true on all
# platforms.
