Original patch from Gentoo:
gentoo/src/patchsets/binutils/2.19/66_all_binutils-2.18.50.0.2-warn-textrel.patch

textrels are bad for forcing copy-on-write (this affects everyone),
and for security/runtime code generation, this affects security ppl.
But in either case, it doesn't matter who needs textrels, it's
the very fact that they're needed at all.
