tools/tracing: Use tools/build makefiles on latency-collector
Use tools/build/ makefiles to build latency-collector, inheriting
the benefits of it. For example: Before this patch, a missing
tracefs/traceevents headers will result in fail like this:
~/linux/tools/tracing/latency $ make
cc -Wall -Wextra -g -O2 -o latency-collector latency-collector.c -lpthread
latency-collector.c:26:10: fatal error: tracefs.h: No such file or directory
26 | #include <tracefs.h>
| ^~~~~~~~~~~
compilation terminated.
make: *** [Makefile:14: latency-collector] Error 1
Which is not that helpful. After this change it reports:
~/linux/tools/tracing/latency# make
Auto-detecting system features:
... libtraceevent: [ OFF ]
... libtracefs: [ OFF ]
libtraceevent is missing. Please install libtraceevent-dev/libtraceevent-devel
libtracefs is missing. Please install libtracefs-dev/libtracefs-devel
Makefile.config:29: *** Please, check the errors above.. Stop.
This type of output is common across other tools in tools/ like perf
and objtool.
