New comment by tornaria on void-packages repository https://github.com/void-linux/void-packages/pull/34209#issuecomment-976109324 Comment: I decided that the sanest thing is to unconditionally disable messing with the fpu control word. In fact, for x86_64* this is unnecessary (it uses sse for doubles) and for i686* this will fall back to `-ffloat-store` (or else one can add `-msse` to `CFLAGS`, then the configure will use sse for doubles and there won't be a need for float-store.
