 Are you sure that it is only perl-net-ssleay that is broken in this way, and
not perl-xml-libxml?

 I tried to run (without this patch)

make perl-net-ssleay BR2_TARGET_LDFLAGS=-g

and that worked just fine. So I suspect the problem is in the system's MakeMaker
package, and not in perl-net-ssleay itself. If that is the case, you should see
the same problem for perl-xml-libxml (because it also uses the LDDLFLAGS, while
other packages don't because they don't build any C code).

 I'm not sure what the real solution would be. Perhaps add a host-perl-makemaker
package and depend on that?

 Regards,
 Arnout
