extending directory selection, --pkglibdir

[Tommi Mäkitalo]

Hi,

I have a library-package, which loads driverlibraries at runtime with dlopen. 
I would like to put these dynamically loaded libraries into a separate 
package instead of $libdir. In automake I have $pgklibdir, but this can't be 
changed with configure, because it is a automake-defined variable defined as 
$libdir/@address@hidden

Now I would like to add a --pkgdir or --driverdir to configure similar to 
AC_ARGS_WITH. Is there any chance to do it without misusing AC_ARGS_WITH?
