If you enable AVX512FP16 or -march which implies it, you need binutils that support such ISA. At least on x86 GCC has behaved that way for years with new ISAs, there intentionally is not a strict detection on which ISAs the assembler can handle, because the binutils used at compile time could be newer than binutils used at compiler configure time. I think AVX512FP16 support went into binutils in early August this year, while 2.37 is from mid July.
