S390: Increase function alignment to 16 bytes.
Set the default function alignment to 16 bytes in order to get rid of some unwanted performance effects. Please see also GCC commit "S/390: Set default function alignment to 16." (Subversion revision 262817) ChangeLog: * sysdeps/s390/s390-64/sysdep.h(ENTRY): Use alignment of 16byte. * sysdeps/s390/s390-32/sysdep.h: Likewise.
