I guess ARCH == mips64 is going to be appropriate for any 64-bit MIPS
target. If you need a different syscall_linux_${GOARCH} file for
different mips64 targets, then I think we're going to need to test some
conditional in libgo/Makefile.am to add the file to build. E.g., look
at syscall_filesize_file.
