i686 is, AFAIK, anything that glibc considers "i686" (i.e. uname -m == i686).
I'd say that's Pentium Pro and above (i.e. Pentium II/III/4). From AMD camp
that's Athlon and above and from VIA it's VIA C3 and above (even though C3
doesn't have the "cmov" instruction, which means you shouldn't use -march=i686
when compiling stuff for it; C3-2 does have it though).
