#66 Missing link against -lm and -lz

[Eric Sandall]

When compiling ripperx 2.8.0 with GCC 5.3.0, zlib is not linked correctly.

Per http://stackoverflow.com/questions/19901934/strange-linking-error-dso-missing-from-command-line , adding "-lm -lz" fixed it. I am not great at the autoconf files, so I just added this before my ./configure and make.

LIBS+=" -lm -lz"
