[Qemu-devel] [PATCH 3/4] build: remove universal-obj-y

[Paolo Bonzini]

All of universal-obj-y, user-obj-y (right now unused) and common-obj-y can
be unified into common-obj-y if we take care of defining CONFIG_SOFTMMU
and CONFIG_USER_ONLY in the toplevel makefile.  This is similar to how
we define symbols for hardware components.
