Full source build for Julia 1.10.2 has broken

As before, but this time's breakage is for no clear reason.

make: *** [checksum-openblas] Error 2

[giordano]

As I mentioned on slack, this may be due to the use of tarballs automatically generated on-the-fly by github, which aren't guaranteed to be stable: https://github.blog/2023-02-21-update-on-the-future-stability-of-source-code-archives-and-hashes/. We should stop using them completely (even if it isn't the cause of the reported issue).

Fixed by #54017.
