Add cross-compile argument

When cross-compiling on SUSE distributions vng fails to find gcc, since it's named '<arch>-suse-linux-gcc', instead of the hardcoded '<arch>-linux-gnu-gcc'. This commit provides a '--cross-compile' argument that will override the hardcoded prefix if used, otherwise it should do nothing. Signed-off-by: Fredrik Lönnegren <[email protected]>
