I'm not sure if tcg/ should move to accel/tcg.  I was thinking of QEMU
runtime files like cpu-exec*, translate*, user-exec.c and cputlb.c.
IMO there's value in leaving the code generator separated from the
QEMU-specific stuff.  I'm also not too enthusiastic about making
accel/kvm and accel/xen for respectively one and three files. :)
So maybe accel/ with accel/tcg/ inside would be enough.

(Also, tcg-runtime.c and tci.c should move to tcg/).

BTW, you can certainly move stubs to subdirectories.  These are
all per-target files, so you can just leave

    obj-y += accel/

in Makefile.target and move the obj-$(...) assignments to the
accel/Makefile.objs file.
