Some distributions (mostly Arch Linux) do not guarantee that a static library is shipped with the library package.
Dynamic libraries, as a contrast, seem to be shipped on all systems, so change the default to OFF, so lo2s should always build when using only dynamic libraries.
Users that require a mostly/fully static lo2s (e.g. HPC) will know what to do.
