Hi,

I enabled --enable-targets=all for all builds on builder.sourceware.org
(with --disable-sim for 32bit gdb builds), which exposed some new
failing tests. I can disable --enable-targets=all again, but maybe it
makes sense to look at the failures and try to fix them.

On fedora-s390x and debian-ppc64 one of the gdb selftests fails
https://builder.sourceware.org/buildbot/#builders/75/builds/783
https://builder.sourceware.org/buildbot/#builders/76/builds/772

Running selftest arm-record.
Process record and replay target doesn't support syscall number
-2036195
Process record does not support instruction 0x7f70ee1d at address 0x0.
Self test failed: self-test failed at ../../binutils-gdb/gdb/arm-
tdep.c:14407

Which is:

  /* 32-bit Thumb-2 instructions.  */
  {
    arm_insn_decode_record arm_record;

    memset (&arm_record, 0, sizeof (arm_insn_decode_record));
    arm_record.gdbarch = gdbarch;

    static const uint16_t insns[] = {
      /* 1d ee 70 7f     mrc    15, 0, r7, cr13, cr0, {3} */
      0xee1d, 0x7f70,
    };

    enum bfd_endian endian = gdbarch_byte_order_for_code (arm_record.gdbarch);
    instruction_reader_thumb reader (endian, insns);
    int ret = decode_insn (reader, &arm_record, THUMB2_RECORD,
                           THUMB2_INSN_SIZE_BYTES);

    SELF_CHECK (ret == 0);
    SELF_CHECK (arm_record.mem_rec_count == 0);
    SELF_CHECK (arm_record.reg_rec_count == 1);
    SELF_CHECK (arm_record.arm_regs[0] == 7);
  }

This seems a big endian issue given the instructions are given as two
16bit numbers.

On debian-ppc64 and fedora-ppc64le there are the following ld failures:
