    mdadm: Do not check RUN_DIR
    
    Fixes build failure on hosts that do not have mdadm
    installed/configured:

    `/local/users/fainelli/openwrt/trunk/build_dir/target-mipsel-linux-gnu_glibc/mdadm-4.0'
    ***** Parent of /run/mdadm does not exist.  Maybe set different RUN_DIR=
    *****  e.g. make RUN_DIR=/dev/.mdadm
    ***** or set CHECK_RUN_DIR=0
    make[3]: *** [check_rundir] Error 1
    make[3]: Leaving directory
    `/local/users/fainelli/openwrt/trunk/build_dir/target-mipsel-linux-gnu_glibc/mdadm-4.0'
