Here we go (finally):

 wget https://buildroot.org/downloads/buildroot-2014.11.tar.bz2
 tar -xaf buildroot-2014.11.tar.bz2
 cd buildroot-2014.11/
 make menuconfig

Target Options:
 Target Architecture = MIPS little endian
 Target Arch Variant = mips32r2
 Soft float = y

Kernel:
 Kernel = y
 Kernel version = 3.6.11
 Kernel config = defconfig
 Defconfig name = mipssim
 Kernel binary format = vmlinux

Toolchain:
 Kernel Headers Version = manually
  linux version = 3.6.11
  Custom kernel header series = 3.6.x

Filesystem images:
 initial RAM filesystem linked into linux kernel =y

... then exit and save the config, and finally type "make".

Then you should be able to run:

 qemu-system-mipsel -M mipssim -nographic -kernel output/images/vmlinux
