Hi all,
LIBTOOL_HAS_SYSROOT feature has been recently enabled on Angstom 2010.x 
distro.

However, using CodeSourcery toolchain, this feature lead to use CSL 
sysroot as search path, that is generally different from 
${STAGING_DIR_TARGET}${libdir} folder used for packages.

At present I worked around the problem with the attached patch, but I 
was wondering if this could be a misconfiguration or a bug.

Any suggestion will be appreciated.

Regards
Gigi
