On the OpenSuSE 10.1 download page there was a link to SGI and at :

  ftp://oss.sgi.com/projects/opensuse/download/inst-source/suse/ia64

was downloadable RPMs for 'ia64-suse-linux', like a recent glibc-2.5 for 
ia64 :

This text seen via 'strings' for the 'lib/libc-2.5.so'...  BUT this was 
almost the only
thing what one could see from the SGI-built glibc :-(   Usual things like :

Dell:/opt/host-SuSE10.1_ia64/lib # ia64-suse-linux-nm libc-2.5.so
ia64-suse-linux-nm: libc-2.5.so: File format not recognized

made with the SuSE10.1 provided 'distcc' ia64-target binutils or with 
self-made ones,
told that there is something weird in the SGI-SuSE Linux binary format...
The "readelf -h" command however gave something :

But it seems that currently producing any crosstoolchains for the SGI's 
'ia64-linux-gnu'
distro by using its original libraries would meet some serious problems :-(

Producing crosstoolchains for the Debian's 'ia64-linux-gnu' with its 
'glibc-2.3.6' then
shouldn't be hard, the Debian packages for ia64 seemed to be quite 
standard Linux/ia64
stuff...

Does someone know what on earth is the idea in the SGI's SuSE 
Linux/ia64, why its
stuff is totally in some non-standard format?
