[Buildroot] [git commit] toolchain: remove the old BR2_VFP_FLOAT option

commit: http://git.buildroot.net/buildroot/commit/?id=d806005b08ec3228a252af4d2f038844a4d6fed2
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Now that we have a much better way of selecting between the various
VFP versions and capabilities, the BR2_VFP_FLOAT version no longer
makes sense. This commit gets rid of it, and adds the appropriate
Config.in.legacy code.
