[PATCH] m68k testsuite TLC

[Jeff Law <law at redhat dot com>]

'twas about to post a fix for an old m68k bug when I noticed the m68k 
target tests weren't clean.  Two minor issues.

First, 20090709-1.c.  It's expecting a definition and two references to 
a string in the constant pool.  However, one reference to that string 
was eliminated in favor of using an integer constant.  This patch 
adjusts the expected output.

Second, pr63347 includes <stdlib>, but doesn't really need it.  Removed 
the #include and added "-w" to the options to keep it quiet about 
missing prototypes and such.

Those two changes make m68k.exp run cleanly.  Committing to the trunk.
