Fails when used in Nix derivation

[dpc]

I'm trying to run cargo hfuzz inside a Nix derivation, which is using crane.

AFAICT, make invocation is trying to create temporary files in the source directory, which is vendored read-only in Nix. It should probably use some OUT_DIR's subdir instead which is meant to be writtable.
