porting glibc to sparc-sun-solaris2

[sbalfour]

We're in a crashy project to port glibc to host sparc-sun-solaris2 and target
mips-*-elf.  I have version 2.2.5.  According to INSTALL, it used to run
on sparc/Solaris 2.x.  It doesn't look like it to me.  It looks like it
is more than a matter of a few tweaks; it looks like infrastructure is missing.
Particluarly, most of the directories have a 'linux' node in their path, and
no corresponding solaris nodes exist.  I don't suppose I'd get so lucky as to
simply rename a linux node to solaris and have it work?  

I'm a little confused by exactly what "run on" an architecture here means.
I'm building the system on Solaris 2.6, so obviously, make and etc have to
"run" on the host.  But the code in the library object modules will of course
match the target system, which is an embedded MIPS core running Cisco IOS.
I don't suppose this would be a problem?  How reliant on the underlying
target OS is it?  It didn't bounce me on target mips-unknown-elf, so I
assume the code will sort of work and sort of doesn't need anything too much
from the target OS.

Anyone working on this port?  Anything you can tell me?
