Fix ARM hardfloat detection in linux

See
  http://code.google.com/p/v8/issues/detail?id=2140
  https://chromiumcodereview.appspot.com/10713009

The original code fails to detect at run-time when compiled
with GCC 4.7, because the undefined behavior of casting
void to double, and the r0/r1 clobbered in assembly code
isn't reaching the use when compared to 1.0 in VFP reg.
In summary, the old code is incorrect and overkill, and the
new code fix it.
