* 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.

Defined if the float format does not support IEEE denormals. Every
float with a zero exponent is taken to be a zero representation.
??? At the moment, there are no equivalent macros above for doubles and
the macros are not fully supported by --enable-newlib-hw-fp.

__IEEE_BIG_ENDIAN
Defined if the float format is big endian. This is mutually exclusive
with __IEEE_LITTLE_ENDIAN.
__IEEE_LITTLE_ENDIAN
Defined if the float format is little endian. This is mutually exclusive
with __IEEE_BIG_ENDIAN.
Note that one of __IEEE_BIG_ENDIAN or __IEEE_LITTLE_ENDIAN must be specified for a
platform or error will occur.
__IEEE_BYTES_LITTLE_ENDIAN
This flag is used in conjunction with __IEEE_BIG_ENDIAN to describe a situation
whereby multiple words of an IEEE floating point are in big endian order, but the
words themselves are little endian with respect to the bytes.
_DOUBLE_IS_32_BITS
This is used on platforms that support double by using the 32-bit IEEE
float type.
_FLOAT_ARG
This represents what type a float arg is passed as. It is used when the type is
not promoted to double.
