build: Use separate makefile for "trace/"
Reviewed-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Lluís Vilanova <vilanova@ac.upc.edu> -- Changes in v2: * Do not depend on "qemu-timer-common.o". * Use "$(obj)" in rules to refer to the build sub-directory. * Remove dependencies against "$(GENERATED_HEADERS)". Cc: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
