re PR target/16350 (gcc only understands little endian ARM systems)
PR target/16350
* config.gcc: For arm*b-* define TARGET_BIG_ENDIAN_DEFAULT.
* config/arm/linux-elf.h (TARGET_ENDIAN_DEFAULT): Define based on TARGET_BIG_ENDIAN_DEFAULT.
Use for MULTILIB_DEFAULTS.
(TARGET_DEFAULT): Set according to TARGET_ENDIAN_DEFAULT.
(LINUX_TARGET_LINK_SPEC): Pass -mlittle-endian on to the assembler.
* config/arm/linux-eabi.h (TARGET_LINKER_EMULATION): Set according to TARGET_BIG_ENDIAN_DEFAULT.
(SUBTARGET_EXTRA_LINK_SPEC): Likewise.
* gcc/config/arm/bpabi.h (TARGET_DEFAULT_MASK): Set according to TARGET_BIG_ENDIAN_DEFAULT.
