[Nix-dev] Disabling patchelf on ARM

[Lluís Batlle i Rossell]

For what I remember, Patchelf is used in most stdenv.mkDerivation just to
shorten the number of dependencies (shrink-rpath).

In armv5tel, I remember that my binaries were broken if I run patchelf
*ONCE*. If I run patchelf *TWICE*, they worked fine. That's clearly an
jnsolved bug worked around. I think it was never fixed in patchelf,
because there was this work-around and noone looked at the problem
anymore.

I think that for arv6 or armv7 the double-patchelf was not required
anymore; I can't tell. I have not checked how does it work now with those
archs.

Jokia, it'd be great if you would gather details beyond "it breaks 
binaries", and even better if you could propose a fix. :)

Regards,
Lluís.
