    buildgcc: work around bug in --print-librt-file-name
    
    Running "clang -target i386-elf --print-librt-file-name" prints
    [..]/bin/../lib/clang/3.6.1/lib/libclang_rt.builtins-i386.a
    
    However, the correct path is [..]/lib/linux/libclang_rt.builtins-i386.a
    on a Linux host. Hence, create symbolic links to make sure that our
    build system finds the file where it expects it.
