Trevor Robinson updated HADOOP-7868:
------------------------------------

    Attachment: HADOOP-7868-portable.patch

This patch fixes the issue using the approach suggested by Daryn: it outputs configure test code that makes use of the library being detected for both zlib and snappy.

>         Environment: Ubuntu Precise, Ubuntu Oneiric, Debian Unstable

> Recent releases of Ubuntu and Debian have switched to using --as-needed as default when linking binaries.
> As a result the AC_COMPUTE_NEEDED_DSO fails to find the required DSO names during execution of configure resulting in a build failure.
> Explicitly using "-Wl,--no-as-needed" in this macro when required resolves this issue.
> See http://wiki.debian.org/ToolChain/DSOLinking for a few more details
