During bootstrapping, cmd/dist writes a file indicating which GOOS/GOARCH combinations are valid, and which support cgo-enabled builds. That information previously went into the go/build package, but today it fits in more naturally in the internal/platform package (which already has a number of functions indicating feature support for GOOS/GOARCH combinations). Moreover, as of CL 450739 the cmd/go logic for determining whether to use cgo is somewhat more nuanced than the go/build logic: cmd/go checks for the presence of a C compiler, whereas go/build does not (mostly because it determines its configuration at package-init time, and checking $PATH for a C compiler is somewhat expensive). To simplify this situation, this change: - consolidates the “cgo supported” check in internal/platform (alongside many other platform-support checks) instead of making it a one-off in go/build, - and updates a couple of tests to use testenv.HasCGO instead of build.Default.CgoEnabled to decide whether to test a cgo-specific behavior. For #58884. For #59500.
