Bring in support for n64 and n32 ABIs, at least at the base.

o Rename __start to __start_mips and change the args a little
o Create a new __start written in assembler that copes with the
  different ABIs and rewrites the args a little to make their passing
  more abi agnostic.
o Add an alias _start for __start for the Cavium toolchain (in the
  cavium port, a custom ld script is used which references _start
  instead of the traditional mips __start).
o call _init_tls() when we aren't being an a.out shared library (which
  is the only time _DYNAMIC is != NULL, I think).  We could likely
  retire support for a.out shared libraries entirely, but that will be
  in the future when I'm sure there's not some subtle reason to keep
  them around.

# Note: the reason mips starts at __start instead of _start is purely
# historical, but I didn't want to change it here and in the
# toolchain.  The Cavium build process is kind of the odd duck here,
# but it is trivial to support both, so why not...
