patch for gdbserver/low-linux.c

[Philip Blundell <pb@nexus.co.uk>]

This patch cleans up some of the machine dependence in low-linux.c slightly 
and adds ARM support.

1999-04-12  Philip Blundell  <philb@gnu.org>

	* config/arm/tm-arm.h (TARGET_ARM): Define.
	* config/i386/tm-i386.h (TARGET_I386): Define.
	* gdbserver/low-linux.c: Test for TARGET_I386 rather than assuming 
	that anything not M68K must be I386.
	(arm_register_u_addr): New function.
