Since the bindings all use usize dont discriminate between 64 and 32 bits

[hansl]

This now builds with "cross build --target armv7-unknown-linux-gnueabihf".

In Rust, usize is u32 in 32-bits and u64 is 64-bits, so theres no need to make a distinction. The extra typings added in this PR will make sure this would compile for the desired target.

Previously the errors given when cross-compiling for armv7 was:
