Add scripts for building a cross-compatible version of TigerVNC on Linux. These build upon the new '-static' option to the build-xorg-7.4 script and add Linux-specific options for statically linking with libgcc, libstdc++, and libcrypto. When used with RHEL 4, these should produce a version of TigerVNC which will work with all later versions of Linux.
