    tools: Introduce str_error_r() · c8b5f2c9

    The tools so far have been using the strerror_r() GNU variant, that
    returns a string, be it the buffer passed or something else.
    But that, besides being tricky in cases where we expect that the
    function using strerror_r() returns the error formatted in a provided
    buffer (we have to check if it returned something else and copy that
    instead), breaks the build on systems not using glibc, like Alpine
    Linux, where musl libc is used.
    So, introduce yet another wrapper, str_error_r(), that has the GNU
    interface, but uses the portable XSI variant of strerror_r(), so that
    users rest asured that the provided buffer is used and it is what is
