Java code will take advantage of it automatically.  Native code must
be recompiled.  The NDK currently only supports soft float, but that
will change in an upcoming release.

Native code is either built for hardware float or compiler-supported
software emulation.  Attempting to use FP instructions on a device
without an FPU will earn you a SIGILL.  The performance of kernel
exception handling is too awful to consider.
