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... :-(

    16 The .s file left behind by -save-temps contains the big long line

    21 The error messages appear to refer to the '1 .get_pic.17', e.g.

    22         .globl 1 .get_pic.l7; .hidden 1 .get_pic.l7;

    23 which seems to come from

    24 glibc-2.3.2/sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h

    25 where it appears originally as

    26         .globl __sparc.get_pic.l7;                                      \

    27         .hidden __sparc.get_pic.l7;                                     \

    28 

    29 Note that __sparc is a predefined symbol on Solaris and some other environments;

    30 it's not surprising to see it predefined on Linux, too.
