[angolini]

It changes the Makefile, so the recipe is the only one controlling the build arguments.

Now it builds

Looks good to me except that the patch cannot be upstreamed as-is. Can you see if there is some way to keep the existing config as the default but overridable by our recipe?

@thochstein I couldn't think of a way to override the default from Makefile. Do you know how?

Another way would be using sed, do you prefer this instead?

I don't know of a better fix off hand, but I think the patch is preferable to the sed operation. Please comment on this in the patch commit message and add an Upstream-Status: Inappropriate [See above].
