    Some explanations in configure.ac regarding static builds
    
    Static builds are a little complicated because all the dependency libraries
    of things like `libcurl' and `libssl' (necessary for `libcurl' and
    `libgit2') will also have to be done statically. An explanation was added
    above the appropriate section in `configure.ac' to help explain this issue.
