Revert "[llvm] Added support for stand-alone cmake object libraries."

This reverts commit 62841415e685fe8857f75edd1fa92b7d1d08b875.

The commit is a misnomer, and it "made its way in" unintentionally,
through a patch that had it as a depdendency. The change itself ended up
to be just a comment update, but the description is completely wrong.
