[Qemu-devel] [PATCH v2 09/25] build: put qom/ rules in a Makefile.objs file

[Paolo Bonzini]

qom/ already used a separate makefile.  Convert it to use relative
paths, and make it declare both common-obj-y and user-obj-y.  This
way, the upper makefiles do not need to know that some QOM files
are compiled twice.
