<machine/ieeefp.h> where it belongs.
o Remove the i386 specific inclusion of <machine/floatingpoint.h>
from <ieeefp.h>, now that including <machine/ieeefp.h> is enough
for all architectures.
o Allow <machine/ieeefp.h> to inline the functions exposed by the
headers by checking for _IEEEFP_INLINED_ in the MI header. When
defined, prototypes are not given and it is assumed that the MD
headers, when inlining only a subset of the functions provide
prototypes for the functions not being inlined.
Based on patch from: Terry Lambert <tlambert2@mindspring.com>
Tested with: make release.
