[OB PATCH][gdb/testsuite] Make noclone conditional in vla-optimized-out.c

[Tom de Vries <tdevries@suse.de>]

Hi,

Make the noclone attribute on f1 in vla-optimized-out.c conditional.  This
makes the test-case by default identical to
gcc/testsuite/gcc.dg/guality/vla-1.c.

Tested on x86_64-linux.

OK for trunk?

Thanks,
- Tom

	* gdb.base/vla-optimized-out.c: Make noclone attribute conditional on
	NOCLONE macro.
	* gdb.base/vla-optimized-out.exp: Use additional_flags -DNOCLONE.
