It is not always a bug.  You can get much more efficient code if you
have text relocations than if you don't.  This "read-only" memory is
perfectly writable until after relocation, a la relro.

But you no doubt will find some non-optimalities (or even straight out
bugs) if you build with -ztext sometimes :-)
