- switch chromium to use clang/llvm instead of gcc
- switch back to the internal libvpx because it's an unreleased version
at this point
- re-enable SSE2 support
switch from using the hacked macosx transport dib to the linux one
which uses sysv shms.
make sure you also have a current kernel before using this version
+ switch from using system sqlite to the bundled one because they have
many modifications that are needed
+ add a new mirror for the distfile because the google one is utterly slow
