S390 ELF core dump currently only contains the PSW, the general purpose
registers, the floating point registers and the access registers stored
in PRSTATUS/PRFPREG note sections.
For analyzing s390 kernel problems additional registers are important.
In order to be able to include these registers to a kernel ELF core dump,
this patch adds the following five new note sections to elf.h:

* NT_S390_TIMER: S390 timer register
* NT_S390_TODCMP: S390 TOD comparator register
* NT_S390_TODPREG: S390 TOD programmable register
* NT_S390_CTRS: S390 control registers
* NT_S390_PREFIX: S390 prefix register

The new note sections have been already defined and accepted in the upstream
binutils package.
