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 Here is a patch for the first possibility.
38 It certainly makes libstdc++.so to link and even the unwind info looks
39 good on brief skimming.
