Thanks for the update, I'm happy with the changes. I would like to see more options for position independent code in embedded systems.

The other related embedded position independent option for microcontrollers that I'm aware of is `-fropi` and `-frwpi` which is already implemented in clang. This is relocation free with just one static data area accessed as an offset from r9. It works quite well for C code, but doesn't support C++ (vtables and RTTI need relocations) and some forms of static initialisation.
