xfsprogs build requires libtool to be installed, but should not

["Kevin P. Fleming" <kpfleming@xxxxxxxxxxxxxxxxxxxx>]

The xfsprogs package uses libtool for building its objects; no problem 
there. However, it requires that libtool be installed on the host 
system during the configure process, but this should not be necessary. 
 The proper way to integrate libtool into a source package includes a 
copy of the final libtool script itself (not the whole libtool 
distribution) _into_ the source package, so that the package can be 
built without the host system needing to have libtool installed.

Can someone look into improving this situation?
