[Buildroot] [PATCH] lua: fix non-shared library build

[Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>]

Building without BR2_PACKAGE_LUA_SHARED_LIBRARY failed because of
missing -ldl.  dl is used by lua's dynamic module loading.

Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>

On ARM, there's still a warning:
ld: warning: creating a DT_TEXTREL in object.

I haven't checked if lua actually works on the target.  But it certainly
won't be worse than before :-)
