linux/mips64: build error

[florianl]

When building this package for linux/mips64 it fails with the following error:

metric/system/cgroup/cgv2/io_helper_linux.go:54:9: cannot use infoT.Rdev (type uint32) as type uint64 in assignment

This is expected as syscall.Stat_t for linux/mips64 defines Rdev as uint32 in https://cs.opensource.google/go/go/+/refs/tags/go1.18.5:src/syscall/ztypes_linux_mips64.go;l=107.

Reproduce with:

$ GOOS=linux GOARCH=mips64 go build ./...
metric/system/cgroup/cgv2/io_helper_linux.go:54:11: cannot use infoT.Rdev (variable of type uint32) as type uint64 in assignment

@florianl Curious what this is being built on. Do we actually need cgroups support on a MIPS system, or can I just change the build rules so MIPS doesn't support getIOStats?

I'm getting this error as well when attempting to build filebeats alone on Ubuntu 20.04.02 running on windows 10 in WSL. Hope that answers your question about what is this being built on...
Sorry, I have no idea what cgroups support means. I would like to build metricbeat as well which means getIOStats will probably be useful. I will be deploying this to some network gear built around a mips64 chip running some flavor of embedded linux.

# build command:
~/golang/beats/filebeat$ GOOS=linux GOARCH=mips64 go build -o filebeat.mips64
$ go version
go version go1.18.5 linux/amd64

FYI I get the exact same error message building for 32 bit mips with the following build command: $ GOOS=linux GOARCH=mips go build -o filebeat.mips32

FYI this is a regression between origin/7.14 and current main af1bcf15dab. $ GOOS=linux GOARCH=mips go build -o filebeat.mips32 succeeded.
