-   Note that we want to give these sections the SHF_WRITE attribute
-   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.  (Note that on SVR4, you may wish to use the
-   `-z text' option to the ELF linker, when building a shared library, as
-   an additional check that you are doing everything right.  But if you do
-   use the `-z text' option when building a shared library, you will get
-   errors unless the .ctors and .dtors sections are marked as writable
-   via the SHF_WRITE attribute.)  */
