linux-user broken for targets with TARGET_ABI32 (i.e. qemu-sparc32plus)

[Matthias Braun]

I just debugged a problem I had with linux-user for qemu-sparc32plus. Turns out that sparc32plus is defined as a 64bit target with TARGET_ABI32 set. This correctly leads to abi_ulong (and others) being defined as uint32_t. However most of the code (in syscall.c) uses tswapl for these values, which swaps the endianess of a target long (which is 64bit). This doesn't match the uin32_t abi_ulongs and fails!

So it appears to me like one would need to define something like an aswapl which swaps abi_ulongs and replace most of the tswapls there...

The fix for this was actually committed way back in 2011...
