ltrace + thumb2

I made a patch for ltrace that adds support for Thumb-2. There's not
much to it, but it allows me to trace applications built for Cortex-A8.
Without it, users will experience this bug:

Unfortunately, it appears that the upstream tree is not well-maintained.
I posted it to the mailing list for the project, but others' patches
have been ignored for many months. However, my post precipitated another
contributor to offer to maintain the package.

I also posted this patch as the proposed solution for the above LP bug,
which should allow Linaro to benefit from the work without worrying
about upstream. In fact, a new version of the package appears to have
been released that includes my patch (0.5.3-2ubuntu6). Please give this
updated package a whirl and let me know if there is more work to be done.

Thoughts? Unless I hear feedback from others, I will assume that this
tool now works for Cortex-A[89] and move on to other tasks.
