For unknown reasons llvm_unreachable() causes a GCC internal compiler error
when cross compiling it for ARM:
/builddir/llvm-3.4/lib/LTO/LTOCodeGenerator.cpp: In member function 'void LTOCodeGenerator::setCodePICModel(lto_codegen_model)':
/builddir/llvm-3.4/lib/LTO/LTOCodeGenerator.cpp:166:1: internal compiler error: in merge_if_block, at ifcvt.c:3193
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Comment it out for now as workaround.
