Subject: [committed] Fix mips/memcpy-1.c after DATA_ALIGNMENT change
Date: Wed, 12 Jun 2013 22:31:57 +0100

Make the array non-common so that it is treated as binding to the
current TU.

Tested on mipsisa32-sde-elf and applied.

	* gcc.target/mips/mips.exp: Handle -f{no-,}common.
	* gcc.target/mips/memcpy-1.c: Remove redundant dg-do.
	Run with -fno-common.
