[PATCH] ARM: use an easier way to create the empty built-in.o

[PATCH] ARM: use an easier way to create the empty built-in.o

[Masahiro Yamada]

We do not have to build an unneeded file to create the built-in.o.
Just add a dummy string to "obj-".
(dummy.c does not need to exist.)

Ah, nice. Adding files just to make the make process happy felt awkward.

Applied, thanks
