upstream "FE_.. constants" patch from void linux?

While considering upgrade of ecl on void linux, I came across this patch

https://github.com/void-linux/void-packages/blob/master/srcpkgs/ecl/patches/fix-math_fenv_h.patch

Reason: Some architectures do not define all of the FE_.. constants

Would it make sense to make a PR here so that it is merged upstream?

Thanks.
