## QEMU.
# Buildroot can also build QEMU, but it does not have SDL support,
# so you have to mess around with a VNC, so let's not use that for now.
# Someone should patch this, and add a SDL support option to the QEMU package! :-)

## Target GDB
# This is preparation for target GDB / gdbserver.
# But those options require a toolchain with threads like glibc,
# which I'm afraid will make compilation slower, so let's leave it
# at that for now since our focus is kernel debug.
