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 	* glibc-compat/nss_dns/dns-network.c (getanswer_r): Reduce

     4 	linebuflen in parallel to bumping up the buffer pointer.

     5 	* glibc-compat/nss_dns/dns-host.c (getanswer_r): Likewise.

     6 	Compare n with linebuflen instead of buflen.
