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. /trunk/scripts/build/cc/gcc.sh | 34 22 12 0 ++++++++++++++++++++++------------ /trunk/config/cc/gcc.in | 35 30 5 0 ++++++++++++++++++++++++++++++----- 2 files changed, 52 insertions(+), 17 deletions(-)

Snapshots are made every friday, at around 22:30 GMT+1,

so look at your calendar to find a suitable date.
