Fix Linux build error w.r.t. Xxf86vm linking
Merge pull request #17 from Lekensteyn/master

Fix build error on Linux.

On some Linux distributions, there is no static libXxf86vm.a, only a shared library. In order to succeed a build, link against the shared library. Since the linker options are the same for 32-bit installations and Solaris, merge the options.
