The intent is to run buildbots that cross-build. All WebKit buildbots build webkit with the script build-webkit (or build-jsc if they only build JSC).

And some architectures are not really powerful, having to build webkit natively on those its beyond reasonable. So the only solution that remains is cross-build.

The current JSCOnly ARM bots http://build.webkit.org/waterfall?category=misc are currently cross-building, and we are setting up a MIPS bot for JSCOnly also (initially).  I'm not sure if they are not hitting this issue (ENABLE_FTL_JIT=ON is passed in the cmakeargs because hostOS==amd64) because the hostOS is a 32-bit one (i686) in their case, or for some other workaround that I missed.
