some questions in the l4 config

[chenggh]

Hi:
	In the drops home directory we could use `make -C l4 config O=./build` to 
enter the l4 configuration interface. There are some options I don't 
understand as following:
	Target Architecture  ---
			(x86) Target Architecture // This is ok and there are 3 options to be 
chosen.
			CPU type: "586" 	//This option is confused because it depends on our input. 
For example If my cpu is pentim4 can I input p4 in the CPU type?  In this 
place is there avaiable small cpu type set? 
		(L4.V2)  ABI 
			(X) L4.V2
			( ) L4.X2
			( ) L4.Sec.(V2.emu)
			( ) Linux
		There are four options to be chosen. L4.v2, L4.X2 and L4.sec are explained 
in other documents. But I choose Linux in this place what can we do?

	Advances:
			[*] Use system-call entry code in the KIP (absolute)
			[ ] Use hierarchical task system (EXPERIMENTAL)
			[ ] Enable RELEASE flag
			[ ] Do not build anything outside l4 directory    

	Please also explain these 4 options.
	Thans very much.
