b9005ba76e S/390: Disable relocation sort against code sections.
When downgrading from GD to IE model we rewrite the call to
__tls_get_offset to a 64 bit load instruction. This relies on the fact
that the additional relocation for the call target has already been
executed when doing the rewrite.

   f1018:       e3 20 d0 00 00 04       lg      %r2,0(%r13)
   f101e:       c0 e5 00 00 00 00       brasl   %r14,f101e <__res_init+0x1e>
                        f101e: R_390_TLS_GDCALL __libc_resp
                        f1020: R_390_PLT32DBL   __tls_get_offset+0x2

0000000f1020  39f6c00000014 R_390_PLT32DBL    0000000000000000 __tls_get_offset + 2
0000000f101e  3afb700000026 R_390_TLS_GDCALL  0000000000000008 __libc_resp + 0

Due to the reloc sorting the order changed an the PLT32DBL reloc is
executed after the rewrite and overwrites part of the load instruction
with garbage.

df88b70224 S390: Place "s390:31-bit" after default arch in 64-bit arch list
On 64-bit platforms GDB did not include "s390:31-bit" in its list of
architecture names.  This patch fixes that.

To determine the list of architecture names for S390,
gdbarch_printable_names() walks through the linked list of BFD arches
starting with the default S390 arch, which is "s390:64-bit" on 64-bit
platforms.  But since "s390:64-bit" was at the end of that list, the
31-bit architecture was not reached.  The patch swaps the elements of
that list on 64-bit platforms.

bfd/ChangeLog:

	* cpu-s390.c (N): New macro.
	(bfd_s390_31_arch): New.  Define only if default target word size
	is 64 bits.  Otherwise define...
	(bfd_390_64_arch): ...this.  Make static.
	(bfd_s390_arch): Define according to the default target word size.
