Hi Guix,

here is another approach to this. This patch series updates jemalloc to
v5.3.0 and does not disable transparent huge pages on aarch64-linux,
similar to what we do on i686-linux and x86_64-linux. So I think this
would support now building binaries for Rust and Icecat on CI for 4K but
also larger kernel page sizes.

Could you please review the patches?

Thanks, Roman.
