first tentative to fix 534695 Nemiver actually is slow when attaching to some targets. This comes from the fact that nemiver steps over the first C instruction it finds when attaching to a program. Stepping over might take a lot of time if for instance there is no debug information for the symbol over which we are trying to step over. In this fix tentative, nemiver instead steps into the next machine instruction instead of the stepping over the first C instruction svn path=/trunk/; revision=821
