Implement (ACFLAGS|CFLAGS|CXXFLAGS).SRC globally.

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.

Add symbol versioning to libm.

Define the LDBL_PREC to be the number of significant bits in a long
double's mantissa.
