Merge commit '5e2203448ab4cc8ea1d933b87f1b39b009201044'

* commit '5e2203448ab4cc8ea1d933b87f1b39b009201044':
  configure: improve the help text for external libraries

Only merged the explanation paragraphs. The removal of "enable/disable"
and "[no]" would create too much inconsistency and might cause
confusion.
