Since http://bazaar.launchpad.net/~squid/squid/3-trunk/revision/12842,
Squid's configure script defaults to -march=native, if the flag is
supported by the compiler. And this even *overrides* your own specified
CPUTYPE or -march= flag!

That could cause squid to crash when using a package that was built on a
newer CPU type that the one where the package would run on.
