By doing this the up coming budgie-extras v1.0.2. doesn't need to be patched for binaries.
The result if we add --bindir=/usr/bin will be:
/usr/bin/free /usr/bin/pgrep /usr/bin/pidof /usr/bin/pkill /usr/bin/pmap /usr/bin/ps /usr/bin/pwdx /usr/bin/slabtop /usr/bin/tload /usr/bin/top /usr/bin/uptime /usr/bin/vmstat /usr/bin/w /usr/bin/watch
Also I should mention that procps-ng source has been moved from sourceforge to gitlab and updated to 3.3.16.
