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... :-( 
     1 Should fix

     2 make[2]: *** [/gcc-3.3-glibc-2.3.2/build-glibc/elf/check-textrel.out] Error 1 

     3 in glibc's "make tests".

    20 Dan, does the attached patch work for you?
