[Qemu-devel] [PATCH v2 40/47] trace: switch target/s390x/ directory to modular trace.h file

["Daniel P. Berrange" <berrange@redhat.com>]

Switch files in the target/s390x/ directory to include the
target/s390x/trace.h file instead of the global trace.h
file.

The make rules for gen-features.{h,c} need to be moved
out into the top level Makefile.objs, otherwise make
complains about the rules being defined multiple times
due to target/s390x/Makefile.objs being included
multiple times when expanding different subdir object
lists.
