Binary release fails with jemalloc error

#850 was closed as fixed, but this still happens in 0.67.0.
(also reported in #872)

I am running Debian 13 on a Raspberry Pi 500 (ARM64), and running the `difft` binary from `difft-aarch64-unknown-linux-gnu.tar.gz`, gives me:

```
$ difft
<jemalloc>: Unsupported system page size
<jemalloc>: Unsupported system page size
memory allocation of 5 bytes failed
Aborted
```
