AIX Subversion Python Swig Bindings fix for core dump

If you're on AIX and Python immediately dumps core when trying to import
any SVN module, then adding "-Wl,-brtl" to LINKFORSHARED in the Makefile
seems to fix the problem.
 
Bad:   > LINKFORSHARED=        -Wl,-bE:Modules/python.exp -lld
Good:  < LINKFORSHARED=        -Wl,-bE:Modules/python.exp -lld -Wl,-brtl

1.	unset PYTHONPATH
2.	./configure --without-gcc --disable-ipv6 --with-thread
CC=/usr/vac/bin/xlc_r CXX=/usr/vacpp/bin/xlC_r 
3.	Edit Makefile:  LINKFORSHARED=  -Wl,-bE:Modules/python.exp -lld
-Wl,-brtl 
4.	make CC=/usr/vac/bin/xlc_r CXX=/usr/vacpp/bin/xlC_r OPT="-O2
-qmaxmem=4000"
5.	make install

Oddly enough, there was no need to build Python using shared libraries.
("#*shared* in Modules/Setup was left commented out and --enable-shared
was not used.)  The OPT="..." is described in
Python-2.5.1/Misc/AIX-NOTES.

This was on AIX 5.3, xlc_r 9.0, Python 5.2.1, Subversion 1.4.5.  It also
appears to work using gcc and Python 2.4.4.

Thanks to Andy Nocera for figuring it out before 'Plan B: Blood
Sacrifice While Doing the Hokey-Pokey' was implemented.
