- pull replacement funcs for fpmacros.c from glibc
This removes the powerpc/classic implementation which did not state any
license but read:

and thus was dubious (and not needed).

float_wrapper. I hope that __ceilf and __floorf are not needed anywhere. Use only __finite from s_finite.c, disabled in fpmacros.c. Allow IMA compiling, 2 files: s_lib_version.c and w_cabs.c have to be reworked for complete IMA.

uClibc's libm has isinf/isinff, isnan/isnanf but not finite/finitef.
Here is a patch.

I found math fpclassify function is broken because FP_XXX definitions
in libm/fp_private.h is incompatible with include/math.h.
Also I noticed fp_private.h and fpmacros.c use many 'long int' for
32bit variables. I think these should be int or u_int32_t.
Here is a patch against 0.9.20.
fp_private.c:
--- fix union members (use u_int32_t instead of 'unsigned long int').
--- remove incompatible FP_XXX definitions (and some unused macros).
fpmacros.c:
--- use FP_NAN instead of FP_QNAN/FP_SNAN.
--- use correct type (int instead of long int).
--- fix union members (use u_int32_t instead of 'unsigned long int').
--- remove unnecessary cast.
Note that I had to remove weak_alias for isnanl,isinfl to compile
patched fpmacroc.c. Is this really needed? Original behavior (using
isnan for isnanl) seems problematic anyway.

_ISOC99_SOURCE, per what glibc does.

of the isinf() macro, which was a casulty of my grafting the
glibc header onto out math library.
