[LinuxBIOS] Various Config.lb fixes.

[Jonathan McDowell]

Hi.

The attached patch fixes up the Config.lb files for the 4 targets that
buildtarget can't currently parse. These are Iwill-dk8s2,
technologic-ts5300, totalimpact-briq & newisys-khepri. None of them then
compile afterwards for me, but this at least gets them one step closer.
Is anyone working on these platforms who has a better fixup for it?

Also, Ollie, any word on the udelay stuff? Can you even give me your
quick hack to get things compiling so I can see if it's hiding any other
problems?
