There are no instances of LLVM_ENABLE_DUMP being emitted during the stage1
build (which is where the failure occurs). Greping for LLVM_ENABLE_DUMP in  the
stage1 build directory only shows...

% grep -R LLVM_ENABLE_DUMP *

include/llvm/Config/llvm-config.h:/* #undef LLVM_ENABLE_DUMP */

Binary file
utils/TableGen/CMakeFiles/obj.llvm-tblgen.dir/SubtargetEmitter.cpp.o matches

   Jack
ps A more general grep for DUMP in CMakeCacne.txt shows...

% grep DUMP CMakeCache.txt
CMAKE_OBJDUMP:FILEPATH=/usr/bin/objdump
LLVM_FORCE_ENABLE_DUMP:BOOL=OFF
LLVM_TOOL_LLVM_CXXDUMP_BUILD:BOOL=ON
LLVM_TOOL_LLVM_DWARFDUMP_BUILD:BOOL=ON
