I don't understand how the one follows from the other.  The binutils and
gcc are separate projects.

The -z now option was added in July 2000, at the same time as -z
nodlopen.  By the way, I suspect that both options were added for
compatibility with the Solaris linker.

Support for -z relro was added in revision 1.113 of elf32.em in May
2004.  The CVS tag history shows that the first binutils release
including -z relro was 2.16.
