unable to build with M1

It seems go should be enough to build local version? That owuld be great for local testing ...

It fails on macbook M1:

$ make build
(re)installing /Users/aslom/Documents/awsm/go/src/github.ibm.com/z-cloud-integration/flowlogs-pipeline/bin/golangci-lint-v1.53.3
/Users/aslom/Documents/awsm/go/src/github.ibm.com/z-cloud-integration/flowlogs-pipeline/bin/golangci-lint-v1.53.3 run --enable goimports --enable gofmt --enable ineffassign --timeout 5m

make: *** [lint] Error 126

Macbook pro 16 M1:

$ uname -a
Darwin m1.local 22.6.0 Darwin Kernel Version 22.6.0: Wed Jul  5 22:22:05 PDT 2023; root:xnu-8796.141.3~6/RELEASE_ARM64_T6000 arm64

$ sw_vers
ProductName:        macOS
ProductVersion:     13.5.1
BuildVersion:       22G90

Here is workaround for current version - if go build fails:

$ go build -ldflags "-X 'main.BuildVersion=0.1.10-rc1-daa0340-dirty' -X 'main.BuildDate=2023-08-30 13:26'" "./cmd/flowlogs-pipeline"
# github.com/netobserv/netobserv-ebpf-agent/pkg/utils
vendor/github.com/netobserv/netobserv-ebpf-agent/pkg/utils/utils.go:76:18: undefined: syscall.Utsname
vendor/github.com/netobserv/netobserv-ebpf-agent/pkg/utils/utils.go:77:20: undefined: syscall.Uname
vendor/github.com/netobserv/netobserv-ebpf-agent/pkg/utils/utils.go:80:42: cannot infer T (/Users/aslom/Documents.../vendor/github.com/netobserv/netobserv-ebpf-agent/pkg/utils/utils.go:84:17)

then patch vendor/github.com/netobserv/netobserv-ebpf-agent/pkg/utils/utils.go

 func currentKernelVersion() (uint32, error) {
-       var buf syscall.Utsname
-       if err := syscall.Uname(&buf); err != nil {
-               return 0, err
-       }
-       releaseString := strings.Trim(utsnameStr(buf.Release[:]), "\x00")
+       // var buf syscall.Utsname
+       // if err := syscall.Uname(&buf); err != nil {
+       //      return 0, err
+       // }
+       // releaseString := strings.Trim(utsnameStr(buf.Release[:]), "\x00")
+       releaseString := "macos"
        return kernelVersionFromReleaseString(releaseString)
 }

then build works:

$ file flowlogs-pipeline flowlogs-pipeline: Mach-O 64-bit executable arm64 ./flowlogs-pipeline -h Transform, persist and expose flow-logs as network metrics ...
