Would -r flag in build.sh command be sufficient to ensure a clean build?

Something like
===> build.sh command:    ./build.sh -m amd64 -B nb899-20190723 -M ../obj -T ../tooldir -r -U distribution kernel=SANDY7

Or would it be necessary to explicitly clean obj and tooldir directories, like
rm -R ../obj/*
rm -R ../tooldir/*
?

At this stage I wouldn't want to keep any remnants from old builds.
