that's indeed the case.

"SSE flags
For silly reasons our default build depends on SSE, but we don't
actually need. Search base/common.gypi and patch out the -msse2 bits
before building your package. "

"Result: layout tests require SSE2, normal builds probably shouldn't
and Google Chrome
packages don't. We don't control other packages."

Don't waste your time reading all the comments on that issue like I
just did. There are hundred of stupid users who posted their cpuinfo
(compare that to this thread where the issue was found after two posts
without much info), and some others trolling.

Just build chromium yourself without sse2, or try to find a binary
which was compiled without it.
If I understood correctly, the .deb packages built there should now be
without sse2 :
