mips: Update elf_machine_load_address for static PIE 

mips uses a local label to compute load address, which works with static
PIE.  We just need to return 0 if _DYNAMIC is undefined for static
executable.

	* sysdeps/mips/dl-machine.h (elf_machine_dynamic): Return 0 if
	_DYNAMIC is undefined for static executable.
