[cfe-dev] Build Clang on x86_64 (ubuntu) with arm-linux-gnueabihf failed

[Anton Smirnov]

As far as i understood, invocation line is saved in
CMakeFiles/llvm-tblgen.dir/link.txt.
I've edited it to remove -L/lib64 and invoked the last command line
manually but the problem remains.

What can i do in order to avoid adding -L/lib64 ?

Thanks,
Anton
