Thanks, applied,

Please consider changing the Makefile to make it be a dependency of the
man pages, so that when we change it we rebuild the man pages, I had to
go fresh to see the results :-)

I.e. had to do this:

Committer testing:

$ git log -1 --pretty="format:%cd" --date=short tools/perf/Documentation/perf-top.txt
2020-01-14

Before:

rm -rf /tmp/build/perf
mkdir -p /tmp/build/perf
make -C tools/perf O=/tmp/build/perf/ install
$ date
Wed 11 Mar 2020 10:21:19 AM -03
$ man perf-top | tail -1
perf 03/11/2020 PERF-TOP(1)
$

After:

rm -rf /tmp/build/perf
mkdir -p /tmp/build/perf
make -C tools/perf O=/tmp/build/perf/ install
$ date
$ date
Wed 11 Mar 2020 10:24:06 AM -03
$ man perf-top | tail -1
perf 2020-01-14 PERF-TOP(1)
$
