Use -mavx2 -mfma instead of -march with AVX2
This was (likely) only a workaround for some early gcc version that did
not support correct AVX2 code-generation with just the -mavx2 -mfma
flags. However, just as with other SIMD flavors with AVX2 too we should
not request arch-specific tuning just to get the desired SIMD flavor
enabled.
