jemalloc test enablement on aarch64-unknown-linux-gnu

[dwn-wwang]

I noticed that currently aarch64-unknown-linux-gnu is listed as not having jemalloc's tests pass on the target, and in the workflow they are disabled with no_tests: 1. However, the workflow does have a ubuntu-24.04-arm runner and it does look like the jemalloc tests pass successfully when I enable them as part of the workflow: https://github.com/dwn-wwang/jemallocator/actions/runs/26426685148/job/77791641911

Was there some context regarding the jemalloc part of the test suite not passing on aarch64-unknown-linux-gnu and/or why they are disabled?

I found these historical possibilities:

• https://github.com/gnzlbg/jemallocator/pull/89/changes
• Syntax error "(" cross-rs/cross#221

in which case I am hopeful the full test suite could be enabled and confirmed passing for aarch64-unknown-linux-gnu

Welcome @dwn-wwang! It looks like this is your first issue to tikv/jemallocator 🎉

hey folks, i'm evaluating whether there is a reason to avoid enabling jemalloc for aarch64-unknown-linux-gnu for linkerd2-proxy's runtime. we had received a ticket (linkerd/linkerd2#15613) with an ask to enable it as well as a PR but i'm hesitant to do that if the tests against jemalloc on aarch64-unknown-linux-gnu are failing
