[llvmlinux] The build is broken

I tested LLVM Linux QEMU with the images from the following site:
http://romanrm.ru/en/a10/qemu

The SD card image booted fine. The SD card mounting problem is not a QEMU
issue.

I tested test3-gcc as well and it also fails so it doesn't look like a
clang issue. It appears to be a kernel configuration issue or an issue with
the current version of the kernel.
