Consider distributing release artifacts built against an older GLIBC (2.28)

[jackh726]

By default, the current github release artifacts don't work on our cluster, because it needs GLIBC 2.29 or newer, but the cluster's GLIBC version is 2.28. I suspect other clusters will also be similarly older, so probably makes sense to build against an older GLIBC. Alternatively (or in addition), could consider building a -musl artifact.

@jackh726 I build most rust software with cargo zigbuild to target older glibc versions (2.17 in this case). Musl builds are in general way slower if progams do a lot of memory allocations:

PATH=/software/zig/zig-linux-x86_64-0.14.1:$PATH cargo zigbuild --target x86_64-unknown-linux-gnu.2.17 --release
