*** Signal 11 -core dumped (ignored)

compiling and linking continues until the new python
executable is invoked to run setup.py and that fails.

I previously built 2.5c1 without all the compile/link
flags above as a vanilla 32-bit app without a problem.

LD_LIBRARY=/usr/ccs/lib/:/usr/lib:/usr/local/lib

the python executable will not start with any command
line option.
