The thing is, binman can emit a lot of files and this is just some of
them. We need a way to handle this in general.

Options I can think of:

- put intermedia files in a subdir
- have a way to ask binman to list the files it would have generated
for any particular board, and 'rm' them in the Makefile
- have binman write out a list of generated files into something like
binman.lst and remove those files
