because these sections will actually contain data (i.e. tables of
addresses of functions in the current root executable or shared library
file) and, in the case of a shared library, the relocatable addresses
will have to be properly resolved/relocated (and then written into) by
the dynamic linker when it actually attaches the given shared library
to the executing process. */
