Hello, I have question about sel4's new ninja build tool.

*1. From now on, sel4-tutorials use ninja build tool, so I repo new sel4-tutorials.Last step, I executue this command "../init-build.sh --plat pc99 --tut hello-1" but It prints with this error messages.What's the problem?---------------------------------------------------------------------------------------------CMake Warning at tools/cmake-tool/flags.cmake:123 (message): Kernel supports hardware floating point but toolchain does notCall Stack (most recent call first): tools/cmake-tool/base.cmake:58 (include) tools/cmake-tool/all.cmake:16 (include) CMakeLists.txt:23 (include)CMake Error at projects/sel4-tutorials/CMakeLists.txt:34 (message): You must select a tutorial for compilation.

How can I build sel4 ia32 images in sel4bench?This command "../init-build.sh -DPLATFORM=ia32 -DHARDWARE=TRUE -DAARCH32=TRUE -DRELEASE=TRUE -DFAULT=TRUE -DFASTPATH=TRUE" doesn't make sel4bench image file.*
