A patch for csu/gmon-start.c

[H . J . Lu]

On ia64, the address of a function is not the address of the
label of the function. To get the address of a function label,
we cannot declare it as a function. Does this patch look ok?

	* csu/gmon-start.c (_start): Declared as "extern unsigned long".
	(etext): Likewise.
