fix compiling warnings with GCC
GCC 7 plus Ubuntu-16.04 default ccache 3.2.4 reports warnings on switch case fall-through code,
which is commonly seen in DPDK code, which will cause image building failure finally.
It requires newer ccache version to support -Wimplicit-fallthrough.
To suppress the warning, if GCC is version 7 or higher, and it's old ccache version,
will disable the fall-through check.
