proc/native: better error message when building on unsupported systems (#1883) As we rearrange the code and the Go compiler changes the error message returned by the compiler on unsupported architectures will change too, making it un-googlable. Since the error message tends to be rather obscure too this regularly confuses newbies. This is an effort to make the error message for unsupported GOOS/GOARCH combinations the same across all unsupported combinations and to make it more user friendly. Directories containing Go source code are supposed to contain a single package. This property happens to be checked by cmd/go itself so it will happen even before the syntax is fully checked and therefore has a high probability of being the first (and only) error message being print. Here we take advantage of this by adding to the pkg/proc/native directory a file with a bad package line that only gets compiled in on unsupported GOOS/GOARCH combinations. At present the error message for compiling Delve on unsupported systems will be: service/debugger/debugger.go:21:2: found packages native (proc.go) and your_operating_system_and_architecture_combination_is_not_supported_by_delve (support_sentinel.go) in $PATH_TO_DELVE/pkg/proc/native 2020-02-24 17:39:51 +00:00			`// This file is used to detect build on unsupported GOOS/GOARCH combinations.`
