Linux obviously
supports multiple architectures (more than any other OS), but it is pretty
stuck to gcc as a compiler (with LLVM just starting to work too).

We are fine with being stuck to a compiler if it gives us what we want.

I beg to disagree.
android, chrome and others changed their kernel builds to
"make LLVM=1" some time ago.
It's absolutely vital for the health of the kernel to be built with
both gcc and llvm.

Our fleet of machines in the data centers is currently mid-ramp, at
around or slightly just over 50% of kernels built with Clang.  Soon to
be 100%.  So "a good chunk of Google services," too, FWIW.

OpenMandriva is on track for their 4.2 release to use LLVM for their kernels.
