* Upgrade lzlib to version 1.3.
* Correct configure flags. It is a C library, not C++. Before it
would always compile with gcc. It only uses CC and CFLAGS.
* Add make check because it's a compression library, and data
integrity seems worth the 2 seconds extra.
Tested on Lion and 64bit Snow Leopard with all compilers from
XCode-4.3.2 and 4.0.2.
