Follow the quoting rule of thumb - if you don't want things expanded
immediately, then use one level of [] per () to protect the argument
collection scan, thereafter, use nested quotes to control how the
expansion is parsed. You want to make sure that UP and DOWN are
independent tokens after the AM_CONDITIONAL is expanded, so this pattern
should do it:
AM_CONDITIONAL([BUILD_DRIVER_[]UP, test "x${use_[]DOWN}" = "xyes"])

Don't work too hard, make some time for fun as well!
