* 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.

@ -203,6 +203,20 @@ Individual component options:
--disable-filters disable all filters
External library support:
Using any of the following switches will allow FFmpeg to link to the
corresponding external library. All the components depending on that library
will become enabled, if all their other dependencies are met and they are not
explicitly disabled. E.g. --enable-libwavpack will enable linking to
libwavpack and allow the libwavpack encoder to be built, unless it is
specifically disabled with --disable-encoder=libwavpack.
Note that only the system libraries are auto-detected. All the other external
libraries must be explicitly enabled.
Also note that the following help text describes the purpose of the libraries
themselves, not all their features will necessarily be usable by FFmpeg.
--disable-audiotoolbox enable AudioToolbox decoders and encoders [autodetect]
--enable-avisynth enable reading of AviSynth script files [no]
--disable-bzlib disable bzlib [autodetect]
