sysinit: Do not open console when just referencing reentrancy structure.
This change eliminates a system initialization dependentcy which resulted
in an application without a file system or console referencing errno being
forced to include the code to open(/dev/console), close(), atexit(),
and the unmount infrastructure.
Closes #4439.
