The linker can select at runtime different sets of libraries depending on
some cpu flags.  I think it can do that for SSE2 just fine, you'd build two
libs: one without interesting intructions, and other with them, and place
them/name them appropriately for that to work, all in the same binary
package.

I think the glibc package does that, you might want to take a look at it.
