[lldb-dev] lldb fails to compile on Linux x86-64

[İsmail Dönmez]

This is from the openSUSE buildbot so its always a clean build. lldb is
placed under tools along with clang (libcxx, libcxxabi is enabled too
fwiw). Exact compile line is:

cmake -G "Ninja" \
      -DBUILD_SHARED_LIBS=ON \
      -DCMAKE_BUILD_TYPE=RelWithDebInfo \
      -DCMAKE_INSTALL_PREFIX=%{_prefix} \
      -DLLVM_LIBDIR_SUFFIX=64 \
      -DLLVM_REQUIRES_RTTI=ON \
      -DLLVM_ENABLE_TIMESTAMPS=OFF \
      -DLLVM_ENABLE_ASSERTIONS=ON \
      -DLLVM_ENABLE_PIC=ON \
      -DLLVM_BINUTILS_INCDIR=/usr/include \
      -DLLVM_TARGETS_TO_BUILD=all \
      -DLLVM_ENABLE_FFI=ON \
      -DLLVM_INCLUDE_TESTS=OFF \
      -DLLVM_ENABLE_LIBCXX=ON \
      ..

Thanks.
