>Description:
MAKEDEV(8) fails when installing -current NetBSD/vax under simh :

     Status: Command failed
    Command: /bin/sh MAKEDEV all
     Hit enter to continue
--------------------------------------------------------------------------------
MAKEDEV: 4: Bad file descriptor

Experiencing with MAKEDEV show that this error occurs for targets that use
makedir() ...

# /bin/sh MAKEDEV all
MAKEDEV: 4: Bad file descriptor
# /bin/sh MAKEDEV zfs
MAKEDEV: 4: Bad file descriptor

I can reproduce it on my amd64 machine with a bogus mtree tool too:

root@lanfeust [/dev]# uname -a

root@lanfeust [/dev]# ./MAKEDEV zfs      
root@lanfeust [/dev]# ./MAKEDEV -t xx zfs
./MAKEDEV: Ignored -t option: xx is missing or broken
./MAKEDEV: 4: Bad file descriptor
