Sebastian Schuberth 497cad7c88 cmake: Teach --build to reject multiple --target options ...

Previously we did not clearly document that `--target` is only supported
to be specified once.  Even worse, specifying it multiple times would
silently ignore any previously specified targets and only build the last
target.

Update the documentation to specify this.  Update the implementation to
reject multiple `--target` options to prevent user errors.
