I don't see why using an external library is going to result in any more
code bloat than writing the equivalent code yourself (especially if you
use -ffunction-sections).

Is there a specific problem with the libffi license?
Even if there is, you could always reimplement libffi (or something similar)
yourself.  That looks like it would be a cleaner solution than hacking
GCC in the way that you described.
