This sounds like there might be a floating dependency in elfutils on
bzip2, if its present. We probably need to lock that down one way or
another.

I've seen mesa-dri-glsl-native myself and if its the same issue, this is
something the signature changes have highlighted. It was there before,
that change just exposed it.

Basically, the problem is compile running twice. You could do it before
with something like:

bitbake mesa-dri-glsl-native
bitbake mesa-dri-glsl-native -c compile -f

We either need to fix these makefile issues or run "make clean" against
them before rerunning make.

Cheers,

Richard
