lzo: fix host-lzo build failure when config cache is filled

When the configuration cache has been filled with a value for
ac_cv_host, host-lzo fails to detect the target system name. This is
due to misbehaving code in the ./configure script. Therefore, we need
to autoreconf the package, which in turn requires :

 * a little fix to the configure.ac file
 * a little fix to src/Makefile.am
 * an extraction of important parts of aclocal.m4 into acinclude.m4

+The lzo tarball only contains an aclocal.m4, which is the result from
+running aclocal. Unfortunately, it lacks the acinclude.m4 file which
+would allow us to do an autoreconf of the package. Therefore, this
+patch extracts from aclocal.m4 the parts that are specific to this lzo
+package, and put them into an acinclude.m4 so that autoreconf on this
+package will work.
