Nope.

Some packages, like apr, only substitute a wrapper header when the
package is built for a multilib arch, but other packages, like gmp,
substitute this header all the time.

So, yes, another solution would be to do it like apr and only
substitute on a multilib arch.  That would solve it as well.
