I have attached a minor update for the Postgres make files. This update

I have attached a minor update for the Postgres make files.  This update
does 2 things:

1) Make it hard to not notice the make failed.  (As you recall, someone on
   the mailing list had this problem.  I've had it to some extent myself).

    The 1.02 make files continue with the next subdirectory when a make
    in a subdirectory fails.  The patch makes the make stop in the
    conventional way when a submake fails.  It also adds a reassuring message
    when the make succeeds and adds a note to the INSTALL file to expect it.

2) Include loader flags on all invocations of the linker.

   The 1.02 make files omit the $(LDFLAGS) on some of the linker invocations.
   On my system, I need one of those flags just to make it invoke the proper
   version of the compiler/linker, so LDFLAGS has to be everywhere.
