Given all the opinions expressed on the list (thanks!), I have decided
to keep the i386 package and make it display an explicit error message
at runtime if there is no SSE2 support in the processor.
Concerning the buildd, I now realize that the package really needs SSE2
support at build time. The reason is that, Julia being a JIT-compiler,
it is run at build time to create the binary image of its standard
library. I'll see if that creates problems on the i386 buildds.
