Turning of JIT for the Qt build by passing "DEFINES += ENABLE_JIT=0" on the command line to qmake works, but "DEFINES += ENABLE_JIT=1" option seems to be broken.
Created attachment 29692 [details] Fix proposal. Make sure the relevant build rules are executed when "DEFINES += ENABLE_JIT=1" passed on the command line to qmake. Also enable turning all JavaScript optimization flags individually on/off.
