Unable to build x86 hosted debugger for ARM Linux, due to missing target

dependencies.  Created ARM Linux specific arm-linux-tdep.c file and moved
missing code into it from arm-linux-nat.c.

2000-04-05  Scott Bambrough <scottb@netwinder.org>

	* arm-linux-tdep.c: New file.
	* arm-linux-nat.c (fetch_fpregs): Remove unused code.
	  (arm_get_longjmp_target): Moved it and all defines
	  it uses to arm-linux-tdep.c.
	  (arm_linux_extract_return_value): Moved to
	  arm-linux-tdep.c.
	* config/arm/linux.mt: Add arm-linux-tdep.c to TDEPFILES.
