Add support for building toolchains with gcc-4.4 snapshots.
Initial patch by Dmitry PLOTNIKOV: http://sourceware.org/ml/crossgcc/2009-03/msg00053.html
It [the toolchain] uses current ct-ng (nightly snapshot 20090324, latest
release 1.3.2 work also), glibc 2.9 (from CVS), binutils 2.19 and latest
snapshot of GCC 4.4.0 (as of March 20, 2009).

We have successfully built linux kernel 2.6.29 and a lot of other stuff
with this toolchain.

Here's the patch that adds GCC 4.4.0 to the ct-ng menu and enables it to
download a 4.4.0 snapshot from ftp.

Patch was adpated by me, mostly to better fit the configuration layout.
