Remove global variable arm_hwcap
After previous patch, we don't need global variable arm_hwcap. This
patch is to remove it.
gdb/gdbserver:
2015-07-30 Yao Qi <yao.qi@linaro.org>
* linux-arm-low.c (arm_hwcap): Remove it.
(arm_read_description): New local variable arm_hwcap. Don't
set arm_hwcap to zero.
