Ports for loong64 arch

[zyppe]

I want to make CDS work on my Loongson workstation (3A5000) , so I tried to compile CDS with make build OS="linux" ARCH="loong64", but make tells me

internal/cdsctx.go:38:9: undefined: keychainEnabled
internal/cdsctx.go:128:12: undefined: storeTokens
internal/cdsctx.go:149:7: undefined: keychainEnabled
internal/cdsctx.go:233:5: undefined: keychainEnabled
internal/cdsctx.go:234:29: cdsContext.getTokens undefined (type CDSContext has no field or method getTokens)

Can anyone tell me what should I do for loong64?
PS: Arch loong64 is official supported by golang
