dCore-trusty, dCore-jessie, dCore-xenial, dCore-stretch, and dCore-artful have been updated in the release candidates area with Busybox 1.27.2.  The new Busybox for these x86 dCore ports was built on dCore-trusty.  dCore-wheezy has too old of GCC to build the newer Busybox based on the errors I saw so it remains with the old version.    
All is working as expected in my testing.
