Here's a wheel which only includes the portable code (I disabled
all the special cases as you suggested).

I didn't run any benchmarks, but it's clear that the SIMD code was
used in my initial build and this adds some 50kB to the .so file.
This is on a older Linux x64 box with Intel i7-4770k CPU.
Could be that the Rust version adds several such SIMD variants and
then branches based on the platform running the code.
In any case, the C extension is indeed very easy to build and
install with a standard compiler setup.
