Some years ago I have made a set of scripts for building MIPS linux kernel and

See https://github.com/frantony/clab for details,

Also see a versatile 'buildroot' software for easy rootfs creation

Run qemu with -S and -s options. Next start your cross gdb (e.g. 
mips-linux-gdb),
next in the gdb cmdline use command "target remote :1234" to connect to qemu.

Do you really need this "in-kernel" gdb support? As I have already write,
qemu itself has gdb server functionality support.
