As a temporary fix my build script creates ar, nm and ranlib as the
following bash script:

    #!/bin/bash

    exe=$0
    exe=${exe##*/} # basename
    cmd="$1"
    shift

    exec PREFIX/x86_64-unknown-linux-gnu/bin/$exe "$cmd" --plugin
PREFIX/libexec/gcc/x86_64-unknown-linux-gnu/GCC_VERSION/liblto_plugin.so
"$@"

(where PREFIX and GCC_VERSION get replaced with the corresponding
values using `sed`)

I'd like to know whether such an approach can cause any issues please?
