Ulrich Weigand da0b1a146f Support powerpc64le-linux platform
This patch adds support for the powerpc64le-linux platform.  It consists
of two main features:

- Support little-endian byte order
  This is done via a "big_endian" member of struct unw_addr_space,
  which is evaluated by common code via the dwarf_is_big_endian
  macro, and also in endian-aware code in unw_is_signal_frame.

- Support the ELFv2 ABI
  This is done via an "abi" member of struct unw_addr_space.  This
  is currently only needed in tdep_get_func_addr, since the ELFv2
  ABI does not use function descriptors.

Both new members are initialized in unw_create_addr_space and
ppc64_local_addr_space_init, following the mips precedent.

Since ppc32 and ppc64 now no longer share the unw_create_addr_space
implementation, the file is duplicated from the ppc directory into
ppc32/ppc64.

Tested on powerpc64-linux and powerpc64le-linux.  Support on LE
seems to be as good as existing BE support; I have not attempted to
fix the existing shortcomings of PPC support that already cause a
number to tests to fail due to unimplemented features.
