Note that eCos does not use an arm-linux toolchain. It needs arm-elf. See
the website for installation instructions. You should have been offered the
choice of downloading a prebuilt toolchain when you installed eCos.

eCos does not build using "configure". Please have a look at the user guide
on how to get started with eCos and the basic concepts:
<http://ecos.sourceware.org/docs-latest/>. The "configure" script that does
exist is there to build some support tools that run on the host. They are
not meant to be cross-compiled at all.

Hope this helps clear things up.
