beagleboard: document how to enable the hard floating point abi
Closes [YOCTO #1203] Using the hard floating point abi is incompatible with some binary libaries and 3D support for the Beagleboard. While we do not provide these in poky and meta-yocto, softfp should remain the default for compatibility reasons. Provide documentation and a commented assignment to DEFAULT_TUNE instructing how to enable hardfp, but leave it disabled by default.
