Subject: Don't invoke mkdir if the directories all already exist.
X-Git-Tag: Release-1-5b~134
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=a5617fc545d6a8ea55a2257e193a14803414fdb1;p=automake.git

Don't invoke mkdir if the directories all already exist.
This saves unnecessary output of "mkdir -p -- FOO" when
FOO already exists.
