Or call it explicitly from the out-of-line tests.
The thing is, if you intend to use this from ifunc tests, I believe
that these can run *extremely* early. E.g. LD_BIND_NOW=1 will run
these while relocating the entire application, and therefore before
any of DT_INIT (aka .ctors), DT_INIT_ARRAY, or DT_PREINIT_ARRAY.
