[PATCH][Doc] Document that you need to use -fprofile-generate when linking also

[Andrew Pinski]

Self explanatory really.  Just document that you need
-fprofile-generate or -lgcov when linking, just like
-fprofile-arcs.

OK?


Thanks,
Andrew Pinski

ChangeLog:

	* invoke.texi (-fprofile-generate): Add that
	you need to link with this option or use -lgcov.
