Patchelf destroys bzip2-shared on ARM

[Volker Braun]

I noticed this on the Sage arm buildbot:

Building bzip2(-shared) from source works:

buildbot@node3eth0:~/Code/bzip2-1.0.6$ ./bzip2-shared 

bzip2-shared: I won't write compressed data to a terminal.

bzip2-shared: For help, type: `bzip2-shared --help'.

Run patchelf the same way hashdist does; Now bzip2 is corrupted:

buildbot@node3eth0:~/Code/bzip2-1.0.6$ ../patchelf-0.8/src/patchelf --set-rpath `pwd` bzip2-shared 

buildbot@node3eth0:~/Code/bzip2-1.0.6$ ./bzip2-shared 

Killed

buildbot@node3eth0:~/Code/bzip2-1.0.6$ ldd bzip2-shared 

not a dynamic executable

It doesn't seem to corrupt all binaries, though bzip2 is pretty early on in the build. Possibly related: https://github.com/NixOS/patchelf/issues/8

In my experience patchelf has limited support for platforms other than x86*.
For example it completely corrupt things on ppc. elfutils works on more
platforms but I am not sure about anything working on ARM.
