[oe] external-toolchain-csl and libtool 2.4

Fri Oct 29 09:29:09 UTC 2010

Thanks for your patches, however the problem is still reproducible 
building libusb-compat with codesourcery toolchain: for some reason, the 
rpath flag is pointing to /usr/lib instead of $lt_sysroot/usr/lib.

The rpath flag, usually not present, is introduced cause generating a 
".lo" file.

Any suggestion?
