[PowerPC/RTEMS] Add 64-bit support using ELFv2 ABI
Add 64-bit support for RTEMS using the ELFv2 ABI with 64-bit long
double.

* config.gcc (powerpc-*-rtems*): Remove rs6000/eabi.h. Add
rs6000/biarch64.h.
* config/rs6000/rtems.h (ASM_DECLARE_FUNCTION_SIZE): New macro.
(ASM_OUTPUT_SPECIAL_POOL_ENTRY_P): Likewise.
(CRT_CALL_STATIC_FUNCTION): Likewise.
(ASM_DEFAULT_SPEC): New define.
(ASM_SPEC32): Likewise.
(ASM_SPEC64): Likewise.
(ASM_SPEC_COMMON): Likewise.
(ASM_SPEC): Likewise.
(INVALID_64BIT): Likewise.
(LINK_OS_DEFAULT_SPEC): Likewise.
(LINK_OS_SPEC32): Likewise.

(TARGET_AIX): Likewise.
(WCHAR_TYPE_SIZE): Likewise.
(WCHAR_TYPE): Undefine.
(TARGET_OS_CPP_BUILTINS): Add 64-bit PowerPC defines.
(CPP_OS_DEFAULT_SPEC): Use previous CPP_OS_RTEMS_SPEC.
(CPP_OS_RTEMS_SPEC): Delete.
(SUBSUBTARGET_EXTRA_SPECS): Remove cpp_os_rtems. Add
asm_spec_common, asm_spec32, asm_spec64, link_os_spec32, and
link_os_spec64.
* config/rs6000/t-rtems: Add mcpu=e6500/m64 multilibs.
