libquadmath: Provide __BYTE_ORDER, __LITTLE_ENDIAN and __BIG_ENDIAN d…

…efinitions My earlier libquadmath change apparently broke mingw32 build, while on Linux <bits/endian.h> is included and defines these, on Mingw apparently that isn't the case, while soft-fp wants a guarantee that sfp-machine.h defines these. 2024-04-09 Jakub Jelinek <[email protected]> * sfp-machine.h (__LITTLE_ENDIAN, __BIG_ENDIAN, __BYTE_ORDER): Define if __BYTE_ORDER isn't defined.
