"bitbake -c populate_dsk_ext" must not trigger do_rm_work, because it
is impossible to declare that the additional tasks activated by "-c
populate_dsk_ext" must run before do_rm_work. When do_populate_dsk_ext
and do_rm_work are both active, the resulting race condition breaks
do_populate_dsk_ext.
The existing bitbake dependencies can't be used for that, because
"addtask populate_dsk_ext before do_rm_work" would then always execute
populate_dsk_ext also in normal builds.
do_populate_dsk_ext triggers do_rm_work indirectly through the
dependency on do_build of the SDK_TARGETs. Using the new
do_build_without_rm_work instead (when available, with do_build as
before if not) avoids the problem.
However, one has to be careful to not trigger do_rm_work in the same
build in some other way. "bitbake core-image-sato:do_populate_sdk_ext
core-image-sato:do_build" still fails, for example. Doing one after
the other works.
