No.  The only thing that needs to be changed is to make the default
libstdc++ atomicity.h correspond to the i486 version not the generic
version.  So, the only breakage would occur would be on i386 in app
using threads in C++.  We could change the default arch to i486 if
desired (and break a lot more apps running on i386), but I don't think
it will affect performance very much.
