The combination of patchelf and strip -S sometimes produces executables that dont work:

$ strace -fF /nix/store/ka8gghwlgbqxm2b387fbpgp4agylm1ss-ghc-6.4.2/lib/ghc-6.4.2/ghc-6.4.2
execve(“/nix/store/ka8gghwlgbqxm2b387fbpgp4agylm1ss-ghc-6.4.2/lib/ghc-6.4.2/ghc-6.4.2”, [“/nix/store/ka8gghwlgbqxm2b387fbp”…], [/* 32 vars */]) = -1 EINVAL (Invalid argument)
+++ killed by SIGKILL +++

Strip also prints out a lot of errors:

And when ld-linux is used directly, it says:

$ /nix/store/m2582n03z3jkq2rba5ll9fkh6zl69ylr-glibc-2.7/lib/ld-linux.so.2 /nix/store/ka8gghwlgbqxm2b387fbpgp4agylm1ss-ghc-6.4.2/lib/ghc-6.4.2/ghc-6.4.2

Worked around by passing dontStrip = true to the ghcboot builder.
