I finally took the time to track and fix this problem of host-lzo
configuration with the shared configuration cache.

The problem was due to the test in ./configure for the target system
name being incorrectly written. Newer versions of autoconf do not
generate such an incorrect code, so the solution was simply to
autoreconfigure the package. Unfortunately, it wasn't so simple, as the
package required several adaptations before being autoreconfigurable.

This is fixed in my for-2010.08 branch, the specific commit being

If you have the time to test this branch and report whether it also
fixes the problem for you, it'd be nice.
