[PATCH RFA] linux-thread.c, lin-thread.c changes

[Kevin Buettner <kevinb@cygnus.com>]

I request approval for committing the changes below.

The lines that read

    #if TARGET_PTR_BIT > TARGET_INT_BIT

cause a compilation error on linux/ia64 due to the fact that
TARGET_PTR_BIT and TARGET_INT_BIT are computed at runtime for the
IA-64 architecture.  (When we get around to multi-arching the other
linux ports, they'll have the same problem.)

	* linux-thread.c, lin-thread.c (save_inferior_pid,
	restore_inferior_pid): Don't do compile time comparison
	of TARGET_PTR_BIT and TARGET_INT_BIT.
