Try

pkgsitedir="$datadir/$PACKAGE_NAME"
eval "expanded_pkgsitedir=\"$pkgsitedir\""
eval "expanded_pkgsitedir=\"$expanded_pkgsitedir\""
AC_MSG_NOTICE([]
   [The modules will be installed in ${expanded_pkgsitedir}.])

but please don't use the expanded value elsewhere; see the FAQ
  info Autoconf "Defining Directories"

and references therein.  Hope that helps.

Cheers,
