[xml] Patch: fix for python installation

[Frederic Crozat <fcrozat mandrakesoft com>]

Hi,

the attached patch fixes python installation for x86-64 (ie new AMD
64bits processor), since libdir = $(prefix)/lib64 for this architecture
instead of $prefix/lib as for other architectures (don't ask me more on
this subject, I'm only forwarding the patch, I'm not the x86-64
specialist :))

If you have comments, please CC: me (I'm not subscribed to the list)..
