We previously included the ImageMagick delegate libraries for both
pgk-config configuration and the *-config files.  However, we got multiple
e-mails and discussion server postings suggesting this was problematic
for a number of packages that depend on ImageMagick.  Now pgk-config
configuration and *-config files only return the ImageMagick related
libraries consisting of Magick, Wand, and/or Magick++.  For example,

  -> Magick++-config --libs
  -L/usr/local/lib -lMagick++ -lWand -lMagick

The delegate libraries should be already linked into libMagick so there
should be no need to include them in the output of the --libs option.
