I used to try to do that, and had many problems with it.  As a result,
I switched to using crosstool-ng to build the toolchain.

I managed to do it, but it required a number of customizations to the
external toolchain makefile, and there were still some minor issues
that required work-arounds in a shell-script that I was using to do
builds.  I eventually gave up and heeded the advice of the
maintainers: now I use crosstool-ng to build my external toolchain.

Using crosstool-ng to build an external toolchain is the normal way of
accomplishing what you want to accomplish.
