我有转到构建器支持的平台列表：
"darwin/386","darwin/amd64","dragonfly/amd64","freebsd/386","freebsd/amd64","freebsd/arm","linux/386","linux/amd64","linux/arm","linux/arm64","linux/ppc64","linux/ppc64le","linux/mips","linux/mipsle","linux/mips64","linux/mips64le","linux/s390x","nacl/386","nacl/amd64p32","nacl/arm","netbsd/386","netbsd/amd64","netbsd/arm","openbsd/386","openbsd/amd64","openbsd/arm","plan9/386","plan9/amd64","plan9/arm","solaris/amd64","windows/386","windows/amd64",我正在研究一个脚本来交叉编译我的项目。我首先将它们包括在内，但现在我在项目中添加了更多代码，因此无法为Plan9进行编译。我抬头看了Plan9，发现它确实很旧，不再使用了。所以我的问题是，实际使用哪些平台并值得对其进行编译？
