libstdc++: Use GCC's predefined macro for endianness [PR104080]
Instead of hardcoded preprocessor conditionals with explicit target
checks, just rely on the fact that __BYTE_ORDER__ is always defined by
GCC.
libstdc++-v3/ChangeLog:
PR libstdc++/104080
* src/c++17/fast_float/LOCAL_PATCHES: Update.
* src/c++17/fast_float/fast_float.h (FASTFLOAT_IS_BIG_ENDIAN):
Define in terms of __BYTE_ORDER__.
