bq. Is this required for 0.15.2?

This is a long-standing bug, I believe it should go in asap...

> We should AC_LIB_CHECK from src/native/configure.ac to ensure libhadoop.so doesn't have
a dependency on libz.so/liblzo.so, the check for libz/liblzo headers via AC_HEADERS_CHECK
is a stronger guarantee anyway.
