Hi,

Yes, we have that in our GUB cross build system.  Possibly this
is a thing/feature request for libtool.

That would be a nice feature.  I expect that if you want to
use this, you should know what you're doing anyway...

No, we only use

    -Wl,-rpath -Wl,'$'ORIGIN/../lib

We do that by postprocessing libtool, substituting the
hardcode_libdir_flag_spec, of course, something like:

  ([('^(hardcode_libdir_flag_spec)=".+"', 
'hardcode_libdir_flag_spec="-Wl,-rpath -Wl,\\$libdir -Wl,-rpath 
-Wl,\'$\'ORIGIN/../lib -Wl,-rpath 
-Wl,/home/janneke/vc/gub/target/mingw/root/usr/lib"')], 
'/home/janneke/vc/gub/target/mingw/build/guile-1.9.14/libtool')

Sure.  Dropping a binary package in a random place is a
common way to do exactly that.

Great, thanks!
