Webkitgtk that is used by dwb and uzbl crashes with illegal instruction when opening a page that has JavaScript on a x86 machine that does not have SSE2. The problem is that the JavaScript JIT creates code with SSE2 instructions.

The solution is to build webkitgtk with the option --disable-jit. Is it possible to have two builds of webkitgtk one with JIT (for those with newest PCs) and without JIT for those that have old machines which dont have SSE2.

I have built a version of webkitgtk on my machine with --disable-jit and it works. Problem is it took ~48hours to do the build so would be nice to have a pre-build one.

Is this still a problem with current webkitgtk packages? If so, we might want to consider enabling the FTL JIT based on LLVM. That could open a whole different can of worms though.
