That's a umask thingy.  Your umask is probably set to 0022, and per
POSIX, mkdir(2) has to take the umask into account.  If you use mkdir(1)
from coreutils:

  mkdir -m 777 /tmp/foo

it should create the permissions as desired, though, since mkdir(1)
sets the umask to 0 if the -m option has been given.
