Subject: Make the usage of alternatives optional through the PKG_ALTERNATIVES
 variable, which is similar to PKG_CONFIG.  This does not change how the
 binary packages are built, only whether the pkg_alternatives command should
 be run at package installation/deinstallation time or not.  The variable can
 take either YES or NO as values and defaults to YES.
