This 'update' breaks qemumips, qemumips64:

Are those machines not even built before master-next is becomes master?

The 1.2 tarball content isn't the same as the v1.2-stable git repo
branch. It's different in non-obvious ways...
I've written to the upstream team to figure out what went wrong:
 
http://lists.nongnu.org/archive/html/libunwind-devel/2017-05/msg00000.html
Note that my first email has not yet been archived. :-/

It's not just a missed commit or two as far as I can tell.
Hopefully they can release a 1.2.1 or 1.3 tarball.


We could use the tarball from the git repo:
 
http://git.savannah.nongnu.org/cgit/libunwind.git/snapshot/libunwind-v1.2-stable.tar.gz
since it has all the mips* support but there was some concern
about the git server going offline periodically, iirc..

For now, I'd like to go back to _git and update the recipe
as Zheng has done in his email:

[OE-core]  [PATCH] libunwind: 1.1 -> 1.2

-PV = "1.1+git${SRCPV}"
+PV = "1.2+git${SRCPV}"

-SRCREV = "bc8698fd7ed13a629a8ec3cb2a89bd74f9d8b5c0"
+SRCREV = "0326f1048a0d75ea9498360f60a0c711cd190b7b"

I'll send that change tomorrow unless there's new from upstream
or someone has a better idea.
