Subject: [PATCH] rs6000: Add support for powerpc64le-unknown-freebsd
This implements support for powerpc64le architecture on FreeBSD. Since
we don't have powerpcle (32-bit), I did not add support for powerpcle
here. This remains to be changed if there is powerpcle support in the
future.

gcc/
* config.gcc (powerpc*le-*-freebsd*): Add.
* configure.ac (powerpc*le-*-freebsd*): Ditto.
* configure: Regenerate.
* config/rs6000/freebsd64.h (ASM_SPEC_COMMON): Use ENDIAN_SELECT.
(DEFAULT_ASM_ENDIAN): Add little endian support.
(LINK_OS_FREEBSD_SPEC64): Ditto.
