Ian,

As discussed several months ago, libgo will not run on mips because it 
references the x86 specific system calls iopl() and ioperm().  These 
system calls do not exist in mips*-linux, so we move them to new 
368/amd64 specific libcall_linux_*.go files.

The attached patch was tested on x86_64-linux-gnu with no libgo 
failures.  There are still some other problems with mips*-linux, but 
this makes forward progress.

It is unclear what kind of change log is required, so I do not supply one.

Cavium, Inc. should now have a corporate contributor license agreement 
on file, so I think you can commit this upstream if acceptable.

Thanks,
David Daney
