Add the full crosstool-NG sources to the new repository of its own.
You might just say: 'Yeah! crosstool-NG's got its own repo!".
Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup.
That means I'm putting backups in place in the afternoon.
That also means we've lost history... :-(

    37 You need something like 1540 to compile 2.4.21 with gcc 3.3.2. 1540 was 

    38 discarded because of AFLAGS change.
