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.

    11       gcc is the full-blown GNU compiler. This is what most people will choose.

    12       

    13       gcc supports many languages, a powerful code parser, optimised binary

    14       output, and lots of other features.

   144       Also, know that crosstool-NG does *not* carry any patch

   145       for the gcc-4.4 snapshots. So, you may have to answer

   146       'y' to CUSTOM_PATCH, and set CUSTOM_PATCH_DIR adequately.
