Clang/LLVM are indeed awesome, and it is good that there is the option to compile the kernel with it.

But I really don't understand all this hate for GCC coming from the Linux kernel guys.

I assume that's mostly because almost every new GCC release breaks kernel building?

Mostly due to kernel developers exploiting nooks and cranies of the current compiler to the hilt, and changes in it break all sorts of unwarranted assumptions... Been there (I routinely compiled the kernel with gcc snapshots way back when) and thoroughly enjoyed the resulting fireworks.
