I guess I did that, yes ;-)
But to make sure:
[acme@zoo linux]$ type perf
perf is /home/acme/bin/perf
[acme@zoo linux]$ rm -f ~/bin/perf
[acme@zoo linux]$ type perf
bash: type: perf: not found
[acme@zoo linux]$ rm -rf /tmp/build/perf
[acme@zoo linux]$ perf
bash: perf: command not found...
Install package 'perf' to provide command 'perf'? [N/y] n
[acme@zoo linux]$ mkdir -p /tmp/build/perf
[acme@zoo linux]$ alias m
alias m='time make O=/tmp/build/perf -C tools/perf install-bin'
[acme@zoo linux]$ m
