--- Comment #11 from Peter Damianov <peter0x44 at disroot dot org> ---
I sent a patch implementing this, along with an extra patch to add
--with-windres= to configure (which I used to test the latter patch).

Binutils will also need a patch to install windres into the "tooldir" otherwise
gcc won't be able to find it in a "typical" toolchain setup.
