The background is that we are to enable hardfp build for chrome browser.
Currently, the '-mfloat-abi=soft' is hard coded in the gyp file, but what we need is "-mfloat-abi=hard", since it is hard-coded, we no way to change it.
So this CL removed this hard-coded value, replaced it with variable arm_float_abi, which has a default value of 'soft'. Later in the ebuild file, we can easily override this value to be 'hard', thus make the build hardfp.
BUG=None
TEST=build manually in chromium
