There are two issues after updating glibc

1. It will fail to build when it reaches the initramfs section because new glibc handles dates differently so busybox will not build so a small patch for busybox is needed.
2. when using debian sources the build will die with Could not find /sbin/mdadm or /sbin/mdmon for initramfs error. reason is this code does not work any more: `[ -e '/sbin/mdadm' ] && LC_ALL="C" ldd /sbin/mdadm | grep -q 'not a dynamic executable'`

I have patches for both issues, the mdadm check is not needed anyway as mdadm is already staticaly compiled
