Ingo reported (again!) that 'make clean' on perf/traceevent does not
work due to some reason with system header file. Quotes Ingo:
"Note that the old dependency related build failure thought to be
fixed in commit 860df5833e46 is back:
make[1]: *** No rule to make target
`/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by
`.trace-seq.d'. Stop.
'make clean' itself does not work in libtraceevent:
comet:~/tip/tools/lib/traceevent> make clean
make: *** No rule to make target
`/usr/lib/gcc/x86_64-redhat-linux/4.7.0/include/stddef.h', needed by
`.trace-seq.d'. Stop.
So I had to clean it out manually:
comet:~/tip/tools/lib/traceevent> git ls-files --others | xargs rm
comet:~/tip/tools/lib/traceevent>
and then things build fine."
Try to fix it by excluding system headers from dependency generation.
