----------------------------+--------------------
 The current code implicitly requires that the code to open /dev/console be
 included in the system initialization set anytime a dependency exists on
 the newlib reentrancy structure. This means that referencing errno pulls
 in at least open(), libio code, close(), atexit(), and unmount support.

 This was shown to result in about 20K of text an 5K of data being included
 in powerpc/psim minimum.exe. A similar impact would happen on all BSPs.
