Do these AVX warnings matter?

I'm a skia newbie and built skia on an old notebook (2012 age) recently. The build succeeded but output many following alike warnings. Do these warnings matter?

../../src/opts/SkRasterPipeline_opts.h:6842:15: warning: AVX vector return of type 'unsigned int __attribute__((ext_vector_type(8)))' (vector of 8 'unsigned int' values) without 'avx' enabled changes the ABI [-Wpsabi]
    auto px = cast<U32>(min(a, 255));
              ^
