Hmmm, looking back through my e-mail, it does appear that I dropped the
ball.

I did get correspondence (months later) from a Sven Neumann about using
libunwind with uclibc.  He sent the patches to me personally but
apparently never to the list.  Looking at the patches, it may be that
these would resolve the issues with using libunwind with uclibc.  I have
never tested these patches nor would I want to sign off on these.

Alternately, I guess I could include the depends on !BR2*<uclibc>*.  Am
I this package owner?  Looking through the repo, I only find one commit
by me: htop.

Either way, if you want me to look at it, I guess I can dust off my
libunwind knowledge and fix 'er up.

Just let me know what ya'll want me to do.  If you would like to see
Sven's patches, I'll shoot those along but will not sign off on those as
I haven't done ANYTHING with those.

Andy
