According to the logs, the 'build-doc' phase fails to compile the
documentation for SIMD related functions. There's a patch disabling this
part of the doc unless we compile on x86_64, but maybe not all x86_64
CPUs have the required instructions...

Would it be possible to get the result of "lscpu" on some machines where
it fails?

The build always works on my machine:
