Hi, vpp experts when i use bihash_init_8_8 ( p, "test"，0，0）function in arm64 machine, it will cause abort() gcc version is 9.3.0
the reason is when buckets is 0, src/vppinfra/clib.h min_log2() function will use count_leading_zero(0), but return value is different between x86 and arm64，x86 is 63 but arm64 is 64, it is a undefined behavior for compiler, so min_log2() need add a judgement with it
