Weird. The Gentoo wiki documents /etc/portage/package.env at...
https://wiki.gentoo.org/wiki/Knowledge_Base:Overriding_environment_variables_per_package
for handling special cases like this. Not every package tests at
runtime. Leaving sse4.1 enabled could result in other packages crashing
with illegal instructions. I don't use chromium. But if I did, I'd use
package.env to handle it as a special case. Chromium is plain weird
anyways. A web browser should not require udev.
