Makefile: Keep trace-events-subdirs ordered
Adding the same directory multiple times to trace-events-subdirs
might trigger build failures, in particular when using the LTTng
Userspace Tracer library as backend.
For example when using two times the hw/core/ directory:
$ ./configure --enable-trace-backends=ust && make
[...]
CC trace-ust-all.o
In file included from trace-ust-all.h:13,
from trace-ust-all.c:13:
trace-ust-all.h:35151:1: error: redefinition of ‘__tracepoint_cb_qemu___loader_write_rom’
35151 | TRACEPOINT_EVENT(
| ^~~~~~~~~~~~~~~~
trace-ust-all.h:31791:1: note: previous definition of ‘__tracepoint_cb_qemu___loader_write_rom’ was here
31791 | TRACEPOINT_EVENT(
| ^~~~~~~~~~~~~~~~
To ease review and reduce likelihood of merge failures (see [*]),
keep trace-events-subdirs ordered when possible, following eb7ccb3c0.
[*] https://www.mail-archive.com/qemu-devel@nongnu.org/msg671007.html
Duplicate trace-events-subdirs entries generates duplicated
symbols when using the LTTng Userspace Tracer library.
