The commit "Fix libarchive linker errors on SunOS for mkdev/major/minor"
hard-coded #include lines for getting mkdev/major/minor on the Sun.
Instead we add missing try-compile tests to make sure the proper headers
get included through the standard mechanism.
This allows for a built in bzip and zip capability, so external tools
will not be needed for these packagers. The cmake -E tar xf should be
able to handle all compression types now as well.
