 Priority:  normal         |  Milestone:  4.12

---------------------------+------------------
 The pc386 BSP has an issue with "ld -r" when function-sections is enabled
 which does not seem to occur on any other BSP. The same lines were added
 to the custom .cfg file as on other BSPs. It is unknown at this point
 whether this is an x86 specific "ld -r" issue or a pc386 build
 configuration issue.

 Per-function-section linking is disabled until this is addressed.
