Issues with trace/Makefile.objs:
1. Generated code is not recreated when patches modify scripts/tracetool/*.py.
Typically such patches also modify trace/*.[ch] and the result is build
failures when new C code compiles against stale generated code.
2. The timestamp mechanism used to avoid unnecessary rebuilding is broken, it
currently requires two make invocations for a full build.

The Makefile uses intermediate timestamp files to avoid rebuilding if
tracetool output is unchanged.
Timestamps are implemented incorrectly. This was fixed for rules.mak in
commit 4b25966ab976f3a7fd9008193b2defcc82f8f04d ("rules.mak: cleanup
config generation rules") but never fixed in trace/Makefile.objs.
The problem with the old timestamp implementation was that make doesn't
notice the updated file modification time until the next time it is run.
It was necessary to run make twice in a row to achieve a full rebuild.

Patches that change tracetool can break the build if old build output
files are lying around.
This happens because the Makefile does not specify dependencies on
tracetool. The build will use old object files that do not match the
current source code.

Fixes broken code and it's cleaner. Thanks!

If 'find' is an acceptable build dependency, I'd rather use this to avoid
missing future sub-directories:
tracetool-y = $(SRC_PATH)/scripts/tracetool.py
tracetool-y += $(shell find $(SRC_PATH)/scripts/tracetool -path "*.py")
If that's not acceptable, I'd suggest forcing expansion in case the variable is
used somewhere else in the future (besides targets, which are always expanded):
tracetool-y = $(SRC_PATH)/scripts/tracetool.py
tracetool-y += $(wildcard $(SRC_PATH)/scripts/tracetool/*.py)
tracetool-y += $(wildcard $(SRC_PATH)/scripts/tracetool/backend/*.py)
tracetool-y += $(wildcard $(SRC_PATH)/scripts/tracetool/format/*.py)
BTW, this was a much needed fix. I ran into problems with this and never even
thought about fixing it :)
Thanks,
Lluis

find is already used in Makefile so it should be safe. Thanks!
