[Cooker] New toolchain

[Gwenole Beauchesne]

Hi,

GCC 4.1.1 and GLIBC 2.4 (CVS) will be uploaded shortly.

Notable changes for glibc:

* NPTL is now the default and linuxthreads are killed. They may be 
revived through a glibc-compat package but not for now.

* I reduced the "multimedia" subdirs to only */lib/sse2/*. I don't think 
mmx and sse1 were much used anyway. If not, please tell.

Bye,
Gwenole.
