From config.log, try reading it.

yasm cannot be found which means you did not install it to somewhere on
your PATH.  What do you get printed if you run yasm --version from the
directory in which you are trying to run configure?

When configure cannot find yasm it then tries nasm.  I find it strange
that nasm should fail as well, especially one provided by apple which
does not recognise that apple format.  Can you also give us the output
of nasm -hf?
