There is a space missing before the "****".

Do we want to link directly against udev or load it at runtime (wine_dlopen)?
For direct linking it would be better to use AC_CHECK_LIB to match the existing
configure.ac code (the only exception I've found is OpenAL). For loading at
runtime there is no need to define UDEV_LIBS.
