Yes, that's codegeneration issue. SPARC code generator needs to override g_external_wrapper method 
and emit something more sophisticated than a simple branch (which is limited to 8 MB in either 
direction).
The stubs that cause a error were not generated by FPC 2.6.2. They were introduced to fix 
http://bugs.freepascal.org/view.php?id=24536

Feel free to report a bug, so it won't be forgotten.
