Presumably, the trapa #33 calls a profile handler in some SH embedded
OS.  You can't do it that way for something heavier-weight like Linux,
so you do need to emit the call to _mcount - however that is done. 

Perhaps write a tiny C program that actually calls _mcount and just
mimic what it does?  It may not have the same calling convention as
normal functions, however.
