'__int128' is not supported on this target

Hi,

your project is used in one or two docker images. Actually, I'm trying to implement multiarch support for those. Possible plattforms are:

Platforms: linux/amd64, linux/arm64, linux/riscv64, linux/ppc64le, linux/s390x, linux/386, linux/mips64le, linux/mips64, linux/arm/v7, linux/arm/v6

Actually I tried i386 and armv6 and building them failed:

Building on a 64-bit arch seems to work fine.

It looks like libffi had similar issues:

https://github.com/libffi/libffi/pull/526 https://github.com/libffi/libffi/issues/531 https://github.com/libffi/libffi/pull/532 https://github.com/spack/spack/issues/16602 https://github.com/spack/spack/pull/17043

Maybe you can look into it, indeed there could also be a problem in how I try to setup things on 32 bit.

Many thank, Jan.

hardened_malloc is only for 64-bit. That's the problem.

Thanks!
