build(release): use native golang toolchain for official release builds (#37828)

Official releases are built by Golang toolchain with CGO disabled.

For packagers who need to cross-compile with CGO, use "build" target
with proper TAGS/LDFLAGS/CGO_CFLAGS to make "$(EXECUTABLE)" target run
the "go build" command.

By the way, drop i386 arch support
