Fixes:

| ldirectord around line 389: =back doesn't take any parameters, but you said =back 4
| ldirectord around line 410: =back doesn't take any parameters, but you said =back 4
| ldirectord around line 489: =back doesn't take any parameters, but you said =back 4
| ldirectord around line 510: =back doesn't take any parameters, but you said =back 4
| ldirectord around line 558: =back doesn't take any parameters, but you said =back 4
| POD document had syntax errors at /usr/bin/pod2man line 71.
| Makefile:756: recipe for target 'ldirectord.8' failed

Also drop the ldirectord file, which is automatically generated.
