Subject: [PATCH] Adjust to Autoconf-2.71

Autoconf-2.71 fixed handling traling white spaces (marked with an
underscore here):

    AC_CHECK_FUNCS( \
      strcpy \
      strdup \
      strchr \_
      strlen \_
      strcat \_
      strtok \_
    )

and correctly converted them to this shell code:

    for ac_func in strcpy strdup strchr \ strlen \ strcat \ strtok \
    do :
      [...]
    done

This patch removes the trailing new lines.
