Hi if we have a aarch64 compiler that has a big-endian
multi-lib, it fails to compile libstdc++ because
simd_fast_mersenne_twister_engine is only defined for little-endian
in ext/random but ext/opt_random.h thinks it is defined always.
OK? Built an aarch64-elf toolchain which has a big-endian multi-lib enabled.
Thanks,
Andrew Pinski
libstdc++/ChangeLog:
* config/cpu/aarch64/opt/ext/opt_random.h: Wrap around with check
for little-endian like ext/random is done.
