Subject: [PATCH] liquid-dsp: don't leak impure builder cpu extensions into the
 build

By default the project builds with automatic vector extension detection
for the cpu. This leaks impure state into the executable and depending on
the builder results in executables that require AVX extensions.

Resolves #384082.
