This commit has broken the RISC-V and AVR experimental builders:
http://lab.llvm.org:8014/builders/llvm-avr-linux/builds/9934/steps/compile/logs/stdio
http://lab.llvm.org:8014/builders/llvm-riscv-linux/builds/1907/steps/compile/logs/stdio

In both cases, due to an undefined symbol when linking libLLVMMC:

error: undefined symbol: llvm::AsmToken::dump(llvm::raw_ostream&) const

I haven't had a chance to dig deeper yet. Any immediate thoughts? I
suspect this is an issue for -DBUILD_SHARED_LIBS=True builds.

Thanks,

Alex
