Add support for enabling and using the binfmt_elf_fdpic program loader
on RISC-V platforms. The most important change is to setup registers
during program load to pass the mapping addresses to the new process.

One of the interesting features of the elf-fdpic loader is that it
also allows appropriately compiled ELF format binaries to be loaded on
nommu systems. Appropriate being those compiled with -pie.

ELF stuff looks fine to me. If the RISC-V folks are happy with the rest,
this looks good.

Please feel free to carry this in the RISC-V tree. If you'd rather it go
via execve tree, please let me know. :)

Thanks for the feedback, much appreciated!
