You need to somehow change the RDEPENDS via one of the mechanisms like
PACKAGECONFIG, or
by splitting the packaging into smaller, more specific sub-packages, etc.

If a package has a RDEPENDS on something else, you can't simply ignore it
or filter it out .. whoever
wrote the recipe is indicating that it is required at runtime. So if you
are saying that it isn't required at
runtime, you should be sending patches to the recipes (and using the
mechanisms like I mention
above) to explain why it really isn't a runtime dependency.
