Allow paths in package.conf to begin with the string "$libdir" which
is magically replaced by the compiler with either

  (a) the argument to the -B<dir> option, if one is present, or
  (b) the wired-in libdir otherwise.

This means that the standard package.conf file is independent of the
install location and we don't need the post-install-script hack any
more (Julian - could you update the install machinery when the time
comes? thanks.)
