json-c: fix build without threads support
An uClibc toolchain that does not support threads emits a warning when _REENTRANT is defined. This breaks build with -Werror. Remove -Werror as a workaround to fix the build. This issue as been reported upstream (https://github.com/json-c/json-c/issues/396).
