[vxworks] testsuite cleanups

[Nathan Sidwell <nathan at codesourcery dot com>]

This patch contains a set of vxworks-specific testsuite cleanups. I'm not sure 
if I can just put my vxworks maintainer's hat on and commit this, so I'll wait a 
few days and commit if no one objects.

	* gcc.target/powerpc/20020118-1.c: Skip on vxworks targets.
	* gcc.dg/20020103-1.c: Check for __ppc.
	* gcc.dg/asm-b.c: Check for __ppc.
	* gcc.dg/20020919-1.c: Check for __ppc.
	* gcc.dg/20020312-2.c: Likewise.
	* gcc.dg/trampoline-1.c: Add appropriate NO_TRAMPOLINES #ifndefs.
	* gcc.dg/torture/asm-subreg-1.c: Skip on sparc vxworks targets.
	* gcc.dg/attr-weakref-1.c: Skip on selected vxworks targets.
	* g++.dg/warn/weak1.C: Likewise.
	* gcc.dg/tree-ssa/20030714-1.c (find_base_value): Declare as
	static so appropriate optimizations kick in.
	(find_base_value_wrapper): New function.
	* g++.dg/eh/simd-5.C: Fix target triplet.
	* gcc.target/arm/long-calls-1.c: Skip for -mlong-calls.
