Subject: autotools: Use make clean for builds not supporting B != S

autotools: Use make clean for builds not supporting B != S

If the build doesn't support B != S, we can try running "make clean" instead
to try and clean up previous objects if the hash for the task has changed.

This tries to ensure that when variables like ${baselib} change, the changes are
correctly accounted for.
