Hello,
I intend checking in the attatched (diff) patch. Before doing it
though, is the s390 really a 31 bit architecture?
For reference I've also included the original diff and ChangeLog.

* s390-nat.c New file Added for S/390 31 & 64 bit target.
* s390-tdep.c Likewise.
* config/s390/nm-linux.h Likewise.
* config/s390/s390x.mt Likewise.
* config/s390/tm-linux.h Likewise.
* config/s390/xm-linux.h Likewise
* config/s390/s390.mh Likewise.
* config/s390/s390.mt Likewise.
* config/s390/tm-s390.h Likewise.
* config.in Added definitions for S/390 31 & 64 bit target.
* configure.host Likewise.
* configure.in Likewise.
* configure.tgt Likewise.
* gdbarch.sh Added 2 definitions to the input table
allow_null_function, this definition is set to an
non empty string if it is okay for the gdbarch function
to be null.
null_function_default_retval, this definiton is the
default return value for a undefined function
(i.e. allow_null_function is defined ).
Added new macros required for S/390
INIT_FRAME_PC_FIRST
CANNOT_STORE_REGISTER
CANNOT_FETCH_REGISTER
ADDR_BITS_REMOVE
EXTRACT_STRUCT_VALUE_ADDRESS_P
Improved the behaviour of the following macros.
PUSH_RETURN_ADDRESS
added allow null function so default behaviour would be correct.
EXTRACT_STRUCT_VALUE_ADDRESS
added check for EXTRACT_STRUCT_VALUE_ADDRESS_P
CALL_DUMMY_BREAKPOINT_OFFSET
* core-aout.c added check for CANNOT_FETCH_REGISTER
in fetch_core_registers.
* arch-utils.c added check for BFD_ENDIAN_UNKNOWN
in set_endian_from_file.
