Yes! Yes! Yes!

You are arguing that white is black.

1) He has a compiled version of x264
2) His compiled version of x264 contains an assertion
3) The assertion asserts that his CPU supports SSE3 or SSE4.
4) His CPU does not support SSE3 or SSE4
5) He needs to recompile x264 such that it no longer asserts that his
CPU supports SSE3 or SSE4.

Your main argument is that in order to do 5), the correct configure
should be something like "--with-asm" and not "--disable-sse3". Well
done, 50 pedant points.
