Any semi-modern toolchain is fine with me. Can you point me at the 4.4
toolchain and I'll put sparc back into my build-test cycle? Thanks!

I have been using this compiler up to now:
http://www.gaisler.com/anonftp/bcc/bin/linux/sparc-elf-4.4.2-1.0.44.tar.bz2
Daniel is that the one you have been refering to?
Regards,
Francois

Then please send me your SSH public key, so I can enable write access
to the SPARC repo for you.
Thanks, and welcome aboard!
Best regards,

I am not familiar with SPARC architecture at all, but
I use kernel.org one for build test.
https://www.kernel.org/pub/tools/crosstool/files/bin/x86_64/4.9.0/
x86_64-gcc-4.9.0-nolibc_sparc-linux.tar.xz
Please note, I have not tested it on any real sparc boards.
