[PATCH] Fix i386_get_longjmp_target

[Mark Kettenis]

This makes i386_get_longjmp_target slightly more "correct", although
it's largely cosmetic.

Checked in.

	* i386-tdep.c (i386_get_longjmp_target): Use
	TYPE_LENGTH(builtin_type_void_func_ptr) instead of TARGET_PTR_BIT
	and TARGET_CHAR_BIT.  Use extract_typed_address instead of
	extract_address.
