[erlang-patches] Erlang build issue on OpenBSD -current

In the mean time, I committed a slight tweak to this to OpenBSD's
ports tree, just additionally defining
DED_LD_FLAG_RUNTIME_LIBRARY_PATH as "$CFLAG_RUNTIME_LIBRARY_PATH".
Patch available at
http://www.openbsd.org/cgi-bin/cvsweb/ports/lang/erlang/patches/patch-erts_configure_in?annotate=1.6.
