FDPIC support on ARM requires a certain target name, and therefore is
only currently available with the Buildroot toolchain. In addition,
only uClibc-ng supports FDPIC on ARM at the moment.

This may need to become more complicated if we end up in a situation
where each libc supports FDPIC on a different set of architectures.
