Update.
* math/math.h: Unconditionally include bits/mathdef.h. Declare
long double functions only if __NO_LONG_DOUBLE_MATH is not
defined.
* sysdeps/generic/bits/mathdef.h: Define only if __USE_ISOC9X.
Define __NO_LONG_DOUBLE_MATH.
* sysdeps/m68k/fpu/bits/mathdef.h: Define only if __USE_ISOC9X.
* sysdeps/i386/fpu/bits/mathdef.h: Likewise.
