Ok, I put it at the same ftp address.
The archive "glibc-2.0.90-970928.debian-tree.tar.gz" installs all Debian files
under "debian" subdirectory.
You have to apply the following patches manually (from debian/patches
directory):
delf-20: kernel patch to compile in batch mode
rtld-sparc: disable profiling
The termios-sparc patch is (partially?) obsolete. Skip it.

Wow!!!
I also discovered a problem with getenv() and __environ variable. Not all
parent environment is available :-(

I guess the bug comes from linker. Can you try a recent binutils (like
2.8.1.0.15)?

Did you recompiled less with the new snapshot?
I think I made a mistake in the previous snapshot that put .rem in the shared
library. In fact, .rem is only defined is libc.a then merged into the program
you compile at link time.
Bye.
