There is one other thing you should be aware of.  --enable-simd=avx will
only run on processors that support AVX. If you force a build to use AVX
and your OS an processor don't support it you will get an error.

In theory you shouldn't need --enable-simd=avx for do it yourself
builds, as the 1.02.000 build process will attempt to use AVX during
compile if supported on your OS and processor. If AVX isn't supported it
will use SSE or SSE2, and if the processor doesn't support any of them
then it will use none. Unless you are experiencing problems, you
shouldn't need --enable-simd=avx .

So this should work:

./configure CC="gcc49" CPPFLAGS="-O3 -funroll-loops -march=native
-mtune=native -I/usr/local/include" LDFLAGS="-L/usr/local/lib"
