+Chromium doesn't officially support 32 bit Linux anymore, and "requires" SSE3. With some workarounds though, it can be made to work.  
+Using the `-msse2` compiler flag is not enough, one must also add the `-mmmx` and `-mfxsr` flags.

-SSE4.1 could be used, for example, for building for a Core 2 Duo system. \
-I make SSE4.2 builds for 1st Gen core, since I have a laptop with a 1st gen "Westmere" CPU.
