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... :-(

     2 "In some cases the specified register for a local variable meant to be
     3 used with inline assembly code is not respected.  This breaks code 
     4 relying on this feature to implement non-standard calling convension."

     6 This fix is probably needed to properly implement linux syscalls in some architectures.
