D'oh! It seems my brain expands anything starting with "L" to LLVM nowadays!
Anyway, llvm-gcc is dead. Ping will need to try clang or dragonegg. I think
there is a metabug describing the status of compiling linux with clang. You
can compile linux with dragonegg, but if you don't take care it will bail out
on uses of "asm goto". The Makefile tests whether the compiler supports "asm
goto", but if you don't pay attention it will just test whether gcc alone
supports "asm goto" (which it does) rather than whether gcc+dragonegg supports
"asm goto" (which it doesn't).
