The problem is with LTO, gcc inlines rte_soring_acquirx_bulk() into
test_soring_stages(). The element copy switches on the runtime
r->esize, so the 16-byte copy path stays live and gcc reports
-Wstringop-overflow writing into the 32 x uint32_t stack arrays.
That path is never taken since the ring is created with 4 byte
elements and metadata.
