Building with OEBasic won't rebuild dropbear to suit IMAGE_FEATURES of
currently build image and even with OEBasicHash I don't know which
dropbear version will be used if I build 2 different images:
bitbake foo-image foo-debug-image

So changing it one way or another is IMHO improvement of current
situation until that bug is fixed properly.
