armv7-unknown-linux-musleabihf suddenly failing tests on latest rust (1.39.0)

fatal runtime error: failed to initiate panic, error 9

qemu: uncaught target signal 6 (Aborted) - core dumped

error: process didn't exit successfully: `qemu-arm /target/armv7-unknown-linux-musleabihf/debug/deps/sheldon-4be4084973670074` (signal: 6, SIGABRT: process abort signal)

I've tested this on the latest cross version, and this seems to work now:

cargo install cross --git https://github.com/cross-rs/cross
git clone --depth 1 --branch 0.6.6 https://github.com/rossmacarthur/sheldon
cd sheldon
cross build --target armv7-unknown-linux-musleabihf
cross test --target armv7-unknown-linux-musleabihf

I didn't use more recent Dockerfiles, since they use musl libc v1.2.0, which uses 64-bit time_t (see #478) which rust and libc don't support yet. The version info I'm using is:

• cross 0.2.1 (459e03e 2022-05-26)
• cargo 1.61.0 (a028ae4 2022-04-29)

Let me know if you want me to try on an older release or tag, since a patch may have changed things. Your CI also suggests the same.
