[PATCH] Remove IRIX 5 <sys/proc.h> _KMEMUSER workaround

[PATCH] Remove IRIX 5 <sys/proc.h> _KMEMUSER workaround

[Maciej W. Rozycki]

Complement commit 3831839c089c ("Delete IRIX support") and remove the 
IRIX 5 <sys/proc.h> _KMEMUSER workaround from the `configure' script, as 
IRIX is no longer a supported host configuration.

	gdb/
	* configure.ac <mips-sgi-irix5*>: Remove <sys/proc.h> _KMEMUSER 
	workaround.
	* configure: Regenerate.
	* config.in: Regenerate.
---
 Strictly speaking we could still support a cross-debugger on an IRIX host 
even if target/native IRIX support has been removed.  Since we've decided 
to dump both target AND host support though, there's no point in carrying 
this piece around.  I suspect this was really needed for native support 
only anyway.

 OK to apply?
