Fix compilation when the armv6 world is being compiled without hw floating
...
point support. The fenv-vfp.c file overrides -mfloat-abi so it can use
floating point instructions if it detects support at runtime. Make it also
override -mfpu in case the user has set -mfpu=none.

Build fenv-vfp.c with the softfp float abi. Without this gcc generates an
...
incorrect assembly file that doesn't allow for vfp instructions.

On armv6 access both the softfloat and, when available, the vfp to get and

set the floating-point environment.

Add a change I missed in r230367 (don't inline arm's fenv.h functions).

Add an implementation of fenv.h intended for platforms that lack an FPU and
...
use softfloat.
Thanks to Ian Lepore for testing and debugging this patch. The fenv
regression tests pass (at least for Ian's arm chip) with this change.
