[Buildroot] [PATCH] support/scripts: tool to create fragments

Interesting, I didn't know this tool existed!

I agree with a name change, however might it be confused (in discussion)
with the other tool? If that is not a problem I would agree with the new name.

Will update the patch to include one along with the changes Matt mentioned.

I actually don't think this would be a best course of action. As it is
written it will work
on busybox or kernel configs, however if we choose to reuse the output
of the diffconfig
tool either logic will have to be added to figure out what configs are
being generated or
another argument will have to specify it and I'm not sure if it is
worth that extra code.

Thanks,

Sam
