[PATCHv2 0/1] Avoid build failures due to setscene errors

[Peter Kjellerstedt <peter.kjellerstedt@axis.com>]

Occasionally, we see errors on our autobuilders where a setscene task
fails to retrieve a file from our global sstate cache. It typically
looks something like this:

WARNING: zip-3.0-r2 do_populate_sysroot_setscene: Failed to fetch URL
file://66/sstate:zip:core2-64-poky-linux:3.0:r2:core2-64:3:\

ERROR: zip-3.0-r2 do_populate_sysroot_setscene: No suitable staging

WARNING: Setscene task
(meta/recipes-extended/zip/zip_3.0.bb:do_populate_sysroot_setscene)
failed with exit code '1' - real task will be run instead

As the last warning indicates, the build will proceed and the real
task will run and the build will eventually complete. However, due to
the two errors above, bitbake will return with an error code which
causes the autobuilder to treat the build as failed and it proceeds to
throw everything it built away.

Since this is quite pointless and causes unnecessary build resources
to be spent and grief from the developers, the two patches in this
change set turn the errors from setscene tasks into warnings.

PATCHv2: The bitbake part has been sent to the bitbake mailing list
instead.
