The alignment is missing for various global symbols in s390 assembly code.
With a recent gcc and an instruction like stgrl this can lead to a
specification exception if the instruction uses such a mis-aligned address.
Specify the alignment explicitely and while add it define __ALIGN for s390
and use the ENTRY define to save some lines of code.

code duplication.

With packed stack the backchain is at a different location.
Just use __SF_BACKCHAIN as an offset to store the backchain.
