i386/soft-float

[Ralf Corsepius]

Hi,

Building newlib currently unconditionally inserts i386-fpu
instructions into libc, which prevents using newlib for i386's w/o
fpu (eg. if using gcc -msoft-float -mno-fpu-ret-in-387). 

To work around this issue, the patch below disables the parts of
libc/machine/i386 which apply floating point instructions if
_SOFT_FLOAT is defined.

Regards
	Ralf
