Yes, see chapter 16.2.1, 'Choosing depends on or select' in the manual:
    http://buildroot.net/downloads/manual/manual.html#_literal_config_in_literal_file

Quoting:
    Note. The current problem with the kconfig language is that these
    two dependency semantics are not internally linked. Therefore, it may be
    possible to select a package, whom one of its dependencies/requirement
    is not met.

He! :-)
