Ingo reported following build failure:
$ make clean install
...
CC plugin_kmem.o
fixdep: error opening depfile: ./.plugin_hrtimer.o.d: No such file or
directory
/home/mingo/tip/tools/build/Makefile.build:77: recipe for target
'plugin_hrtimer.o' failed
make[3]: *** [plugin_hrtimer.o] Error 2
Makefile:189: recipe for target 'plugin_hrtimer-in.o' failed
make[2]: *** [plugin_hrtimer-in.o] Error 2
Makefile.perf:414: recipe for target 'libtraceevent_plugins' failed
make[1]: *** [libtraceevent_plugins] Error 2
make[1]: *** Waiting for unfinished jobs....
Currently we have the install-traceevent-plugins target being dependent
on $(LIBTRACEEVENT), which will actualy not build any plugin. So the
install-traceevent-plugins target itself will try to build plugins,
but..
Plugins built is also triggered by perf build itself via
libtraceevent_plugins target.
This might cause a race having one make thread removing temp files from
another and result in above error. Fixing this by having proper plugins
build dependency before installing plugins.
