Roadmap is intent for future development, not secret branches that are
already finished. :-)

(Well, the switchover to time64 is kinda such a branch, but the
patches have been posted on the list.)

Anyway, now that the FDPIC ABI is upstream in GCC, it can definitely
happen. To make it easy to go forward, I need to get a version of GCC
that ARM FDPIC patches will apply to supported in musl-cross-make.
After that it shouldn't be hard to make it work.
