Please don't embed the full canonical build path into the solution for this.
It seems possible to vary the build path successfully and produce the same
output (see bug 68848 for a minor fix needed for debugging symbols), so it
would be a shame to re-embed it here.

using a cryptographic digest of the file contents would require roughly the
same Makefile trickery without forcing a canonicalized build path.
