## This test checks that:
## - __mod_init_func is replaced by __init_offsets.
## - __mod_init_func has type S_INIT_FUNC_OFFSETS.
## - initializers show up in the order their parent objects are specified on the
## command line, and in the order they show up within __mod_init_func.
## - for undefined and dylib symbols, stubs are created, and the offsets point to those.
## - offsets are relative to __TEXT's address, they aren't an absolute virtual address.
