proposed fix for no-rpath

  Hi,

  I rewrote the no-rpath test. For that, I supposed that no-rpath was a simple hello-world program compiled with default options (-Wall -g -O2). This seems to do the trick.
  To keep the test for a different architecture, I precompiled this source. I did it on various Debian architectures so that tests are wider. Note that the ia64 binary test fails. I mark it as an expected failure for now, but I think that this is probably a bug in patchelf.

  Please, pull my work and create an official release (as a downloadable tar.gz file) so that I can create an official Debian package.

  Regards,
    Vincent

PS: is there any reason why you cherry-pick all my previous commit without modifying them instead of merging them?
