[Linux-ia64] latest glibc snapshot does not build on ia64?

Haven't dug into this too much yet; wanted to see if anyone else has
seen this?

Yup.

There's a short glibc patch which takes care of this (should be on the
Debian lists, else I can mail it to you once I get my machine back up).
It's an "unofficial"  patch because it's felt the problem really lies 
with binutils and not glibc, so it's not in glibc cvs.   The change
is to dl-machine.h if it helps search...

there was a IA64_RELOC_NONE patch, but in a different area of glibc...
looks like we just hit it again at a different spot now...


    580   /* ??? Ignore MSB and Instruction format for now.  */
    581   if (R_IA64_FORMAT (r_type) = R_IA64_FORMAT_64LSB)
    582     *reloc_addr = value;
    583   else if (R_IA64_FORMAT (r_type) = R_IA64_FORMAT_32LSB)
    584     *(int *) reloc_addr = value;
    585   else if (r_type = R_IA64_IPLTLSB)
    586     {
    587       reloc_addr[0] = 0;
    588       reloc_addr[1] = 0;
    589     }
    590   else
    591     assert (! "unexpected dynamic reloc format");

r_type is 0 at the assertion

It's actually the same spot, but the context has changed a bit.  Here is
an updated patch:
