Subject: Makefile's: Only create non-existing directories
X-Git-Url: https://arthur.barton.de/gitweb/?p=ax-unix.git;a=commitdiff_plain;h=a028a2ed10390a41babfaa49204a2360e8c2389f;hp=79574a461a0c3693bb9f250fd85062d0459b9db6

Makefile's: Only create non-existing directories

This prevents the install(1) command to fiddle with owner, group and
permission information of already existing items (which could fail).
