Because the wrapper is not available everywhere, and going through a wrapper in
order to fix a missing thing in dmd is just a workaround. DMD(FE) should be
able to do this natively.
When adding support to Meson/CMake/Automake/Makefiles, telling users that they
need the compiler but also this other tool which - in the Meson world - has the
sole purpose of supplying a missing functionality in DMD is pretty cumbersome.
It's a workaround, but no real solution to the issue.

At the moment, Debian/Uhuntu/Fedora/OpenSUSE and probably a couple of other
don't ehip rdmd at all, which makes demanding it just to work around this bug
not worthwile anyway.
