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

N.B. you need to use a forward slash here, not backslash.

(defined) is not the right component name here.

But I fixed it differently anyway, see PR 104080.
