I support deleting the soft-float multilib; it can't be used as-is because 
it requires its own libc, in its own sysroot, and the configuration 
doesn't use a separate sysroot for it.  As for -mstrict-align, again if 
someone wants -mstrict-align libraries I think they should set up a 
multilib using that option (or a CPU option that implies it) rather than 
trying to make the libraries from a compiler configured for some CPU 
compatible with another CPU they wouldn't normally be compatible with.
