If it's only ever called once then no, but if there's any chance it 
might be called more than once then yes it makes a difference.

Currently every package build is running "mkdir ${WRKDIR}/.pkginstall" 
at least 21 times, for example.

Might not take that long in isolation, but this work is really about 
making lots of small changes add up to a huge improvement.
