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

[Anton Smirnov]

I can confirm that after editing there is no -L/lib64 in invocation line,
but the problem remains. I think previously compiled files were
compiled/linked with -L/lib64 and this
corrupts the build.

How can it be fixed/walked-around?
