Comment (by bgamari):

 I have posted `0004-reproducible-tmp-names.patch` as Phab:D4220.

 The remaining patches are:
 * `0000-bootstrap.patch`: This seems quite suspicious. Moreover, it very
 likely won't be needed in Hadrian.
 * `0002-Correct-issue-with-libffi-and-glibc.patch`: Someone is going to
 need to take ownership of this to get it upstreamed into `libffi`
 * `0005-buildpath-abi-stability.patch`: This doesn't seem like a
 reasonable approach as it kills potentially useful information in the
 interface file. Either we should find a way to encode this information in
 a deterministic way (e.g. module name and unit ID) or remove it entirely
 if it really isn't necessary
 * `0007-build-hp2ps-twice.patch`, `0008-build-unlit-twice.patch`: Looking
 at these again, they actually look fairly reasonable. In general we
 shouldn't pollute the final build artifacts with things produced by the
 bootstrap toolchain. I would say we should just fix this in Hadrian. I've
 opened #14501 to fix this.
