/*
 * 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 returned.
