OK, Rust 1.55.0 was just released without this particular patch. So in order to
get it to work on x32, we will have to include the patch from [1].

Subject: [PATCH] Change more x64 size checks to not apply to x32.
Commit 95e096d6 changed a bunch of size checks already, but more have
been added, so this fixes the new ones the same way: the various size
checks that are conditional on target_arch = "x86_64" were not intended
to apply to x86_64-unknown-linux-gnux32, so add
target_pointer_width = "64" to the conditions.
