[PATCH] python-native: configure unicode to ucs4

[PATCH] python-native: configure unicode to ucs4

[Eric Bénard]

* while trying to run gdb from an SDK created by OE, I got the following
errors: /usr/local/angstrom/arm/bin/arm-angstrom-linux-gnueabi-gdb: undefined symbol:
PyUnicodeUCS2_FromEncodedObject

* the reason is that the workstation (ubuntu 10.04 or 9.01)'s Python is compiled using ucs4
and the python-native used to create arm-angstrom-linux-gnueabi-gdb is using ucs2, the
problem is detailed here :
http://docs.python.org/faq/extending#when-importing-module-x-why-do-i-get-undefined-symbol-pyunicodeucs2

* configuring python-native with ucs=4 solves this problem.

Can you test this out on some form of Red Hat?  Thanks!

generated SDK tested on Fedora Core 10 : it works.

As discussed on IRC, I RedHat is compiling it's python wuth ucs=4 at 
least since RedHat 7 from what I saw in the SRPMS.
