Upgrade to glibc-2.19
Adjust alignment for the devtab and linker funcs

The new gcc apparently wants us to have 64 bit alignment for the devtab.
We oblige accordingly.  Also changed the alignment for the linker
function sections preemptively.  Not as clear whether we needed to do
this or not, but the change was necessary for the devtab.
Add new patch to busybox for including a header
