add little endian support
This adds support for building LE skiboot with LITTLE_ENDIAN=1.
This is not complete, notably PHB3, NPU* and *CAPI*, but it is
sufficient to build and boot on mambo and OpenPOWER POWER9 systems.
LE/ELFv2 is a nicer calling convention, and results in smaller image and
less stack usage. It also follows the rest of the Linux/OpenPOWER stack
moving to LE.
The OPALv3 call interface still requires an ugly transition through BE
for compatibility, but that is all handled on the OPAL side.
