Pretty complicated because of some annoying decisions taken by the gcc
team. The problem is that gcc won't let you use intrinsics unless the
file is compiled with -march=pentium3 (or higher). Unfortunately, this
means you have to put all the SSE stuff in another file, which is
complicated for some of the Speex files. Also, you have to find a
portable way to get the build system use different compilation switches
for different files. Last thing, it also makes the detection function
less trivial.
