[PATCH 0/4] FDPIC support

[Nicolas Pitre]

This series provides the needed changes to suport the ELF_FDPIC
binary format on no-MMU ARM. This format has many advantages over
the FLAT format such as being actual ELF which can be parsed by
standard tools, can support shared dynamic libs without fuss, etc.

A complete toolchain and prebuilt packages can be found from here:
