failed to build libpq.so on AIX 4 and 5/I have a solution

I'm posting this report to pgsql-bugs@postgresql.org too.  I aware the fact
that I posted mostly the same report to pgsql-bugs@postgresql.org about two
month ago.  Though, I had a mistake on it.  I needed -Wl, before -bnoentry
to support gcc.

Please enter a FULL description of your problem:
------------------------------------------------
I tried to build PostgreSQL on AIX 4 and 5 but failed to build libpq.so.



Please describe a way to repeat the problem.   Please try to provide a
concise reproducible example, if at all possible:
----------------------------------------------------------------------
./configure --enable-multibyte=EUC_JP --with-CC=gcc
make




If you know how this problem might be fixed, list the solution below:
---------------------------------------------------------------------
You need to specify -bnoentry option for ld when you build shared library,
on AIX 4 or later.  Here is a patch.  This works for xlc too.
