CFLAGS="-march=amd64 -O2 -pipe -fomit-frame-pointer" CHOST="x86_64-pc-linux-gnu"
I could be wrong, but I didn't think amd64 was a proper -march flag.
if your CHOST is x86_64, and you installed from a proper amd64 stage tarball, then you don't need an -march flag if you're using gcc-3.3.x:

however, gcc-3.4 you can choose from here:
