        * libc/include/machine/ieeefp.h: Change to only define
        floating point defines (e.g one of __IEEE_BIG_ENDIAN or
        __IEEE_LITTLE_ENDIAN must be defined for each platform).
        * libc/include/sys/config.h: Include <machine/ieeefp.h> and
        remove redundant floating point definitions.
