Tried to build on an old core2duo machine. configure did not add the right -march=core2 flag so SIMD extensions failed to build.

Had to do. export CFLAGS="-march=core2" before running configure. Then it built ok.

Does https://github.com/jgaeddert/liquid-dsp/pull/65 fix this for you? (You have to rerun autoconf and configure after applying this patch)
