The cp27/cp22m/win32 bits are selected automatically based on target
platform (it's the "tags" mechanism, see the Wheel PEP)  Nick is suggesting
that the version with no sse will always be selected by default, but the
user can supply some sort of command line argument saying effectively "if
you have a sse2 variant, give me that one instead".
