Syscall parameters are already swapped by the caller.
This patch removes useless tswap() from strace.c
$ QEMU_STRACE=1 chroot /m68k mknod myramdisk b 1 1
with tswap()
...
29944 mknod("myramdisk",026630200000) = 0
...
without tswap()
...
30042 mknod("myramdisk",S_IFBLK|0666,makedev(1,1)) = 0
...
natively:
$ strace touch mytouch
...
open("mytouch", O_WRONLY|O_CREAT|O_NOCTTY|O_NONBLOCK, 0666) = 3

The current print_mmap func is only enabled when the target supports the
mmap syscall, but both mmap and mmap2 syscalls use it. This leads to a
build failure when the target supports mmap2 but not mmap.

Howabout something like this:
commit eb8387cb0eda32a18880664eb5f0ca5c8bf05b45
Author: Riku Voipio <riku.voipio@iki.fi>
Date: Thu Jun 18 22:44:31 2009 +0300
Subject: linux-user: include futex defines directly
Since some common distributions have broken linux/futex.h, stop
including it. Instead add the defines directly.

- to not to break strace with GUEST_BASE is set:
- Strace now can load and print guest strings correctly.
- Added printing support for commonly used flags in some syscalls
(e.g open, creat, mmap etc.)
v2:
- fix strace.c build on etch
- add futex print to strace
