Numeric-13 build failure on Python 1.6a2

     I'm getting a build failure with Numeric-13 with Python 1.6a2.  There
seem to be two problems at work here:

   ---------------------------------------------------------------------------
1) The first problem is the linker tries to link for the wrong architecture.

   When makesetup writes $(LDSHARED) command-lines, it doesn't include 
   $(LDFLAGS) on that command-line.  In Python's config/Makefile,
   LDFLAGS=-n32 here on IRIX.

   It's this line in makesetup that writes these link lines:

                rule="$rule; \$(LDSHARED) $objs $libs -o $file"

   If I add \$(LDFLAGS) to it, we're past that hurdle.

   ---------------------------------------------------------------------------
2) The second problem is that in Python's config/Makefile, it has:

      LDSHARED=       ld

   But it should be:

      LDSHARED=       ld -shared

   As a result, when Numeric goes to link a shared object, it inadvertantly
   tries to link it as an executable, which of course fails.
   Changing this declaration as described above fixes problem #2.

   ---------------------------------------------------------------------------

Before I add this to the bug database, could someone confirm that these are
the right fixes for this problem?

Thanks,

Randall
