I'm writing a script that downloads sixgill and gcc from people.m.o, unzips them in a directory, builds SpiderMonkey with the custom gcc, and finally runs the analysis. I don't know if it's the right thing to have this in-tree, but since I'm doing it...

You may want to warn that you will need to be on Fedora/CentOS/RedHat, or another distro that installs libstdc++ in the same place that they do. (Specifically, the prebuilt GCC won't work on Ubuntu without the CFLAGS and CXXFLAGS settings from and Ubuntu is pretty common.)

Uh, what the heck is that git thing doing in there? Seems redundant, and on my system it spews
