Update libm_hard.a

1) Add ldexp.  ldexp used to co-exist in both libc.so and libm.so until
   the removal from libm.so in ICS.  Unfortunately the sole copy of libm_hard.a
   in NDK was compiled from JB source and miss ldexp.  Code compiled with
   hard-float using ldexp may use libc.so which follows soft-float and misbehave
2) Turns out the following (all in fpclassify.o) also exists in recent libc.so
   too.  Add them in libm_hard.a as well:

    __fpclassifyd
    __fpclassifyf
    __fpclassifyl
    __isfinitef
    __isfinite
    __isfinitel
    __isinff
    __isinf
    __isinfl
    __isnanl
    __isnormalf
    __isnormal
    __isnormall
    isinf
    isnan
    isnanf
