Your patch seems to be newline damaged. It can't be applied directly. I
suggest that you use 'git send-email' to avoid patch mangling.

When no support SSL backend is available you should explicitly disable
SSL support. I believe something line this would work:

else
LIBUWSC_CONF_OPTS += -DUWSC_SSL_SUPPORT=OFF
endif

Just do

ifeq ($(BR2_USE_MMU)$(BR2_PACKAGE_LUA_5_1)$(BR2_PACKAGE_LUA_5_3),yy)

That works because only one lua version can be enabled for a given
configuration.

But why is MMU required, actually? I see no fork() call in the code.

Here again lua support should be disabled explicitly in the 'else' part.
