* config.gcc (powerpc*-linux*-*): Add support for 64-bit little
endian Linux systems to optionally enable multilibs for selecting
the long double type if the user configured an explicit type.
* config/rs6000/rs6000.h (TARGET_IEEEQUAD_MULTILIB): Indicate we
have no long double multilibs if not defined.
* config/rs6000/rs6000.c (rs6000_option_override_internal): Do not
warn if the user used -mabi={ieee,ibm}longdouble and we built
multilibs for long double.
* config/rs6000/linux64.h (MULTILIB_DEFAULTS_IEEE): Define as the
appropriate multilib option.
(MULTILIB_DEFAULTS): Add MULTILIB_DEFAULTS_IEEE to the default
multilib options.
* config/rs6000/t-ldouble-linux64le-ibm: New configuration files
for building long double multilibs.
* config/rs6000/t-ldouble-linux64le-ieee: Likewise.
