* Add versions 8.0.16, 5.7.26, and 5.6.44
* Update boost dependency for versions 8.0.16, 8.0.15, and 8.0.14
* Update dtrace script when building for versions before 8 as is done
  for the glib package
* Set perl as a build dependency for versions before 8
* cxxstd=17 conflicts with version 8 when server code is built
  (~client_only)
* Add -Wno-deprecated-declarations for cxxstd > 11
* Add -Wno-error=register for cxxstd > 14
