It's on the todo list, it just hadn't been a priority until somebody
expressed an interest.  Now you have. :)

Current source control is using unstable repository versions of both
uClibc and Linux, so it doesn't work with much.  (I'm attempting to
wrestle NPTL to the ground, then go back and clean stuff up.  Right now,
the NPTL build doesn't want to work with sjlj exceptions, which is a bug
on their end but I could also just switch to dwarf exceptions and see if
that fixes it.  Presumably all the targets support that now...)

Cool.  It wasn't working in the last uClibc release, but that was in the
Pleistocene so I'm glad to see this get some attention.

(Getting a new target to work is always a pain: your problem could be
toolchain, libc, kernel, qemu, driver selection, kernel command line.
And getting a target to work after some time away from it, any of those
and more can bit-rot...)

There should be a sparc-strip in the cross and native toolchains.  Try that?

Thanks,
