How to include "libbfd" support in cross-gcc setup?

[Toralf Lund]

I just found that I have to support some software using "libbfd" in my 
gcc cross compilation setup. On my older installations I don't have a 
libbfd, so I'm rebuilding the cross compiler so that it may be provided...

But how exactly is this supposed to be done? I mean, it seems to me that 
I somehow have to build this lib in a separate step. I libbfd build is 
done already, of course, but as far as I can understand, this will 
provide binaries suitable for link into the cross compiler and related 
tools, as opposed to link into cross-compiled applications (which is 
what I want.)

I suppose one way of doing it is to add another build step that starts 
with something like

mkdir build-bfd; cd build-bfd
../binutils-*/bfd/configure --target=${cross_target} 
--host=${cross_target} --prefix=${sysroot}

And I'm actually testing this right now. But is this the "correct" way? 
Or the best way? Is anyone else doing anything like this? How?
