Unfortunately the logs are long lost; I clean out TMPDIR quite
regularly (but retain sstate). This makes perfect sense and is most
likely what happened; I probably noticed I was missing libSDL-devel
when I built qemu from git by hand :-) In any case restoring my old
sstate and doing

    $ bitbake -c cleansstate qemu-native
    $ bitbake -c cleansstate nativesdk-qemu

cleaned everything up for me.

Should YP be trying to build its own copy of libSDL (with the -devel)
if it finds some part of libSDL (i.e. the header files) is missing
from the host? This is almost like a "host contamination" issue, no?
