Comment (by gk):

 Okay. Some status report here. The mscvr100 is getting linked (according
 to the dependency walker). Just put the LDFLAGS _before_ configure is run,
 put in the proper path to the libmsvcr100 and get rid of -nostdlib (and
 probably -lgcc; it does no harm to not have it currently). Now, that's the
 good news. The bad news is that the Tor Browser is now even failing to
 start on Win7 showing the error message: "missing entry points for
 _strcmpi in msvcr100.dll". I tried several things to get that issue
 solved, so far without any luck. The weird thing is that Tor Browser
 itself does not use this function at all. So, not sure who is actually
 needing it (my attempts to trace the function calls failed badly). My best
 bet is a possible interference with the still linked msvcrt (where
 _strcmpi is indeed still available)). That brings us probably closer to
 the need of recompiling the lib*.dlls we ship (as well), which is already
 looming on the horizon. I still hope we can avoid that, though...
