The default definitions (from sysdeps/unix/sysv/linux/Makefile) would I
suppose go some suitable location based on where they end up being used;
those in sysdeps/unix/sysv/linux/x86_64/Makefile would I suppose end up in
sysdeps/x86_64/Makefile (likewise for other architectures). I don't have
a detailed design, it simply seems that there is a lot in common between
the different cases of multiarch headers (even though bits/syscall.h is
one header working for all subarchitectures while the others involve a
wrapper header round different variants for each subarchitecture).
