    Stop assuming no-debug-info functions return int

We now have to explicitly tell GDB the type of the non-debug-info
function we want to print (by casting).  This commit adjusts the
"print" statement on gdb.arch/i386-sse-stack-align.exp to do the
proper cast, fixing a failure that started to happen after the
mentioned commit.
