Many Thanks Andrew. I have finally sorted it out although i think my eyes are giving up on my after careful comparing lots of files. It turns out that line 2 of my custom build step had the -S missing from it so gcc was trying to assemble and link the file rather than just compile it.
Many thanks, no I can proceed.

The "-priority 1" controls when this section of make script is
executed. See:
http://ecos.sourceware.org/ecos/docs-latest/cdl-guide/build.make.html#BUILD.CUSTOM
One guess as to why it does not do it is because the dependencies are
wrong somehow. It thinks the target is up to date so there is no need
to rebuilt it. Deleting the file should force it to rebuild it.
