The `contrib/refresh_checksums.mk` script does not create or update the checksums for the `libunwind-1.3.2.tar.gz` file

When running make USE_BINARYBUILDER=0 on Buildkite, I get the following error, caused by the fact that some checksums are missing for the libunwind-1.3.2.tar.gz file.

Check that the working directory is clean
ERROR: The working directory is dirty.

@staticfloat @vtjnash How can I add the necessary checksums? I tried running both of the following commands, but neither command added the checksums that I need.

make -f contrib/refresh_checksums.mk unwind
make -f contrib/refresh_checksums.mk llvmunwind

[DilumAluthge]

Is there a way that I can get contrib/refresh_checksums.mk to use the USE_BINARYBUILDER=0 make flag?

I tried make -f contrib/refresh_checksums.mk unwind USE_BINARYBUILDER=0, but when I look at the output, it is still passing the USE_BINARYBUILDER=1 make flag.

refresh_checksums.mk already has a provision for USE_BINARYBUILDER=0, it's the src targets, which is set for all BB_PROJECTS, of which unwind is a member.

If you run:

$ make -f contrib/refresh_checksums.mk unwind
make -s -C "/home/sabae/src/julia/deps" USE_BINARYBUILDER=0 FC_VERSION=7.0.0 UNWIND_BB_TRIPLET= LLVM_ASSERTIONS=0 DEPS_GIT=0 checksum-unwind

You see that it actually runs the USE_BINARYBUILDER=0, but it fails out because when USE_BINARYBUILDER=0 is set, apparently checksum-unwind is not defined, whereas it is when USE_BINARYBUILDER=1. Why doesn't the overall command fail? Because we allow failures of these steps because of the second attempt, where we blindly try to download unwind for a triplet that it's not supported for. What a beautiful little microcosm of build system agony.

So the solution here is to just fix the name of the from-source checksumming target: #42630
