[Qemu-devel] [PATCH] trace: Fix user emulator dependency on trace objects

[Qemu-devel] [PATCH] trace: Fix user emulator dependency on trace objects

[Andreas Färber]

On a clean build, after generating trace.h, make would recurse into *-*-user
without a clue how to build ../trace.o (added to $(obj-y) in Makefile.target)
since its generation rule is in the main Makefile.
The softmmus are seemingly unaffected because the $(TOOLS), which each have
a dependency on $(trace-obj-y), are built first for the build-all target.

Add a dependency on $(trace-obj-y) for %-user, as done for the qemu-* tools.

Let's be paranoid and do the same for %-softmmu while at it, just in case
someone messes with $(TOOLS) or calls the Makefile target directly.

Doing the same for %-softmmu was a good idea and helped me, thanks.

Ping? 7 days, one ack, one thank-you from the original author. Could  
someone please commit or comment please? This fixes a broken build  
configuration on all platforms.

Thanks,
Andreas
