 It looks like some BSPs with their own linkcmds may have shrunk too much.
 Norm appears to be 50% while some went to 75-80%. A second look after

 linker scripts were not correct and it was missed.

 Rather than reverting a bunch of patches, this ticket is to review all
 function-section patches from this one back in time for cxx_iostream
 shrinking too much.
