OK, but in release mode for instance, the <debug-symbols>off resolves to the
'-s' option which results in the same executable as when it's stripped. So
just saying debug symbols need to be on when profiling solves this.
Maybe a solution is to define <debug-symbols> as neither being on or off but
I'm not sure if this can be done , e.g. like this :

variant profile : release :
<profiling>on
<debug-symbols>
;
