perf: disable parallelism for 'make clean'
Whenever perf got rebuilt, I was consistently getting errors such as
| find: '[...]/perf/1.0-r9/perf-1.0/plugin_mac80211.so': No such file or directory
| find: '[...]/perf/1.0-r9/perf-1.0/plugin_mac80211.so': No such file or directory
| find: find: '[...]/perf/1.0-r9/perf-1.0/libtraceevent.a''[...]/perf/1.0-r9/perf-1.0/libtraceevent.a': No such file or directory: No such file or directory
|
[...]
| find: cannot delete '/mnt/xfs/devel/pil/yocto/tmp-glibc/work/wandboard-oe-linux-gnueabi/perf/1.0-r9/perf-1.0/util/.pstack.o.cmd': No such file or directory
breaking the whole build. The root cause seems to be that the implicit
'make clean' done during do_configure ends up running in parallel, and
thus multiple find commands attempt to stat and/or delete the same
file.
A patch disabling parallelism for the clean target has been ack'ed
upstream (lkml.kernel.org/r/20180705134955.GB3686@krava), but it should
be harmless to pass JOBS=1 even with a fixed kernel. This can be removed
if and when all relevant -stable kernels have that patch.
