* Makefile.am (MATHOBJS_IN_LIBC): Add s_isinfd, sf_isinff,
        s_isnand, and sf_isnanf object files.
        * Makefile.in: Regenerated.
        * libc/include/ieeefp.h: Undef isnan and isinf to avoid
        conflict if <math.h> has previously been included.
        * libc/include/math.h
        * libm/common/Makefile.am: Add new s_isinfd, s_isnand, sf_isinff,
        and sf_isnanf files.  Also support s_isnan, sf_isnan, s_isinf, and
        sf_isinf files which have been moved from math/mathfp directories.
