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.
