[PATCH 07/12] bsps: Avoid line continuation in Makefile.am

[Chris Johns]

Is it a requirement for Makefile.am we avoid line continuation?

I had a choice and wrapped lines in the testsuites and without any guidelines I
choose a more compact format. It was easy to do with python's textwrap module.

At some point I think it would be good to collect together what we want to do
with Makefile.am files as some form of a coding standard. I have some things
that might go in like conditionals ..
