Hello

The stat64/fstat64 syscalls are broken for alpha linux-user.

This is because Alpha, even though it is native 64-bits, has a stat64 
syscall that is different than regular stat.  This means that the
"TARGET_LONG_BITS==64" check in syscall.c isn't enough.  Below is
a patch that fixes things for me, although it might not be the cleanest 
fix.

This issue keeps sixtrack and fma3d spec2k benchmarks from running.

Vince
