[PATCH 1/7] Move have_ptrace_getregset to linux-low.c

[Yao Qi <qiyaoltc@gmail.com>]

This patch moves variable have_ptrace_getregset from linux-x86-low.c
to linux-low.c, so that arm can use it too.

gdb/gdbserver:

2015-07-28  Yao Qi  <yao.qi@linaro.org>

	* linux-x86-low.c (have_ptrace_getregset): Move it to ...
	* linux-low.c: ... here.
	* linux-low.h (have_ptrace_getregset): Declare it.
