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.
