- New upstream version 2.2.6
    - Remove --enable-pae as that requires a CPU level of 6 with the new
        version
    - Remove a few configure switches which are identical to the upstream
        defaults and thus don't do anything
    - Add --enable-clgd54xx
    - Add --with-svga which adds support for svgalib as display
    - Fix compile with wxGTK-2.6 and unconditionalize wxGTK build
