Commit
70a56b914772e6b21cda2a5742817ae4bb7290f1 introduced a regression.
If utils/mkdir-p.pl fails to create a target dir because of insufficient file system
permissions, the subsequent test for dir existence always fails and overwrites
the system error. As a result, a user is presented with a misleading error message.
E.g. if a user tries to create a dir under /usr/local and does not have permissions
for it, the reported error message is "Cannot create directory /usr/local/lib: No such file or directory",
whereas the expected error message is "Cannot create directory /usr/local/lib: Permission denied".
This commit introduces a fix by declaring an additional local variable to cache
the original error message from mkdir. If -d check fails and overwrites the system
error, the user is still presented with the original error from mkdir.
