libtool is now longer renamed to ${host}-libtool, so remove the changes
to support this.
This means that apr now installs libtool into the build-1 folder, but
as this has never been needed before (as we use the system libtool) we
can remove it (it contains build paths so is unreproducible). Also add
a RDEPENDS on libtool for the target -dev package.
