# particular you must ensure that the binary containing the resolver
# is relocated before the resolver is called (for example, the
# function addresses returned by the resolver may be loaded from the
# GOT).
# That does not happen for the pr23169 testcase where the resolver is
# in the executable (which is relocated last by ld.so).
