[PATCH v2] json-c: Make implicit-fallthrough only a warning for compilation under icecc

[PATCH v2] json-c: Make implicit-fallthrough only a warning for compilation under icecc

[Douglas Royds]

icecc preprocesses source files locally before shipping them off to be compiled
on remote hosts. This preprocessing removes comments, including /* fallthrough */
comments in switch statements that normally prevent the implicit-fallthrough
warning. Rather than turning off -Werror completely, just reduce
implicit-fallthrough to a warning only.

In the -native case, we might be building on an earlier gcc, eg. gcc 5.4
under Ubuntu 16.04, so we do disable -Werror completely.

Please disregard this one, I have submitted a newer patch under a new 
subject-line:
