Ah, you built binutils, but did you put them on your path?
You need
   PATH=$PATH:/opt/gcc/bin
before you configure gcc.  Then it should pick up mipsel-linux-as
from the path.

But as Kai says, this isn't the list for this sort
of question.  You should take it to the crossgcc list
http://sources.redhat.com/ml/crossgcc/
(where we will tell you to try http://kegel.com/crosstool :-)
or the etux list
http://www.embeddedtux.org/mailman/listinfo/etux
(which is explicitly for people who don't like using canned scripts
like crosstool.  In other words, for people like Kai :-)
