scripts: Set the compiler warning options to "-Wall -Wextra -Wundef"
Considering that "-Wextra" is a more descriptive alternative to "-W", and that "-Wundef" is a highly useful warning option that has been available in ancient versions of gcc (version 2.x), we replace all occurrences of "-W -Wall" with "-Wall -Wextra -Wundef". Also clean up the makefiles.
