meson changed to use $ORIGIN for the builddir for reproducible builds so
that the size allocated to store the builddir doesn't change according
to what it is, changing the size of the final binary.

I understand why you wouldn't want $ORIGIN in the final binary, but this
isn't the issue.

I see that cwrappers operate on rules, but where are these rules defined?
