yann@1069: Original patch from Gentoo:
yann@1069: gentoo/src/patchsets/binutils/2.19/66_all_binutils-2.18.50.0.2-warn-textrel.patch
yann@1069: 
yann@1069: textrels are bad for forcing copy-on-write (this affects everyone),
yann@1069: and for security/runtime code generation, this affects security ppl.
yann@1069: But in either case, it doesn't matter who needs textrels, it's
yann@1069: the very fact that they're needed at all.
