DL_LAZY is only needed for future compatibility, as stated in the
OpenBSD 3.0 man page.
man dlopen reports:
"The path argument can either be an absolute pathname or it can be of
the form ``lib<name>.so[.xx[.yy]]'' in which case the same library
search rules apply that are used for ``intrinsic'' shared library
searches.  The second argument currently has no effect, but should be
set to DL_LAZY for future compatibility."
