bindgen_test_layout_max_align_t test fails on i686 on cryptoki-sys crate

[nullr0ute]

When running the tests with bindgen for i686 the tests fail due the size of max_align_t

test bindgen_test_layout_max_align_t ... FAILED

Hey! Thanks for reporting, looks very similar to the same one you reported on psa-crypto (here). We can apply the same fix.

I figured it was probably similar, I had forgotten about that report, there's also the same issue on the tss-esapi-sys. Seems like a theme ;-)

Alright created a PR on both repos:

• Fix a bindgen test failing #13
• Fix a failing bindgen test rust-tss-esapi#215

By the way, are you compiling those crate with the generate-bindings feature? If you wanted we could add the targets to the list of supported ones so you wouldn't need the bindgen dependency.

Yes, on this only arm/aarch64/x86_64 was created, on tss-esapi-sys only x86_64 was created. We build for armv7/aarch64/i686/x86_64/ppc64le/s390x so we needed to use bindgen to generate the pieces for all the arches.
