Hi, Tim,
I start to consider something about 32bit on 64bit platforms.  Could
you explain "do the syscall list for 32bit IA32 on x86_64"?  Do you
mean set up a *new* syscall list for 32bit IA32 on x86_64?

ppc32 has the same syscall list as ppc64, so I add
LinuxPowerPCSysca.java for both, and it is easier to do bi-arch on
PowerPC w.r.t Syscall.  As this patch has been checked in, the
syscallList(target specific) could be returned via isa type of that
task, when a 32-bit(ia32) program running on x86_64, syscallList for
Ia32 could be indexed by its syscall number.
