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... :-(

     3   rtld.c: In function '_dl_start':
     4   dynamic-link.h:47: error: nested function 'elf_machine_rela_relative' declared but never defined
     5   dynamic-link.h:41: error: nested function 'elf_machine_rela' declared but never defined

    10 and

    12 which seem to propose less radical fixes?
