to work because: legacy architectures used the wrong end of the
frame for the ID.stack (inner-most rather than outer-most) so
that the callee's id.stack (un adjusted) matched the caller's
id.stack giving the "correct" id; more often than not
!IN_SOLIB_DYNSYM_RESOLVE_CODE and hence the code above (it was
originally later in the function) fixed the ID by using global
