Changing the ThinLTO config to a choice and moving it after the main
LTO config sounds like a good idea to me. I'll see if I can change
this in v8. Thanks!

Originally, I thought this might be a bit ugly once GCC LTO is added,
but this could be just a choice like we're done for the stack
initialization. Something like an "LTO" choice of NONE, CLANG_FULL,
CLANG_THIN, and in the future GCC, etc.

Having two separate choices might be a little bit cleaner though? One
for the compiler (LTO_CLANG versus LTO_GCC) and one for the type
(THINLTO versus FULLLTO). The type one could just have a "depends on
CC_IS_CLANG" to ensure it only showed up when needed.

Cheers,
Nathan
