mips: Update elf_machine_load_address for static PIE
Commit Message
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.
OK for master?
* sysdeps/mips/dl-machine.h (elf_machine_dynamic): Return 0 if
_DYNAMIC is undefined for static executable.

OK.
