-[PATCH] libubox: drop legacy json-c support
-
-The cmake logic is wrong (E.G. PKG_CHECK_FOR_MODULES fails unless all
-modules are found), and the legacy libjson.so name is also used by the other
-libjson (http://sourceforge.net/projects/libjson/) which provides an
-incompatible API, so just drop it.
