+ help
+ With this option uClibc provides non-functional stubs for
+ functions which are impossible to implement on the target
+ architecture. Otherwise, such functions are simply omitted.
+
+ As of 2008-07, this option makes uClibc provide fork() stub
+ on NOMMU targets. It always sets errno to ENOSYS and returns -1.
+
+ This may be useful if you port a lot of software and cannot
+ audit all of it and replace or disable fork() usage.
+ With this option, a program which uses fork() will build
+ successfully. Of course, it may be useless if fork()
+ is essential for its operation.
