From: LiaoShihua <shi...@iscas.ac.cn>
When I built riscv-gcc with newlib, it will be terminated with message "fatal
error: endian.h: No such file or directory".
So, fixed it in fast_float.h.
libstdc++-v3\ChangeLog:
* src/c++17/fast_float/fast_float.h (defined):fast_float.h will include
<machine/endian.h> with using newlib
