我正在使用 crosstool-ng 交叉编译 AVR GCC 以在 Android 上使用。我需要使用 LTO 支持 (-flto和) 编译它，-fuse-linker-plugin从而传递CT_STATIC_TOOLCHAIN=y, CT_CC_GCC_USE_LTO=y,和in 。CT_CC_GCC_ENABLE_PLUGINSCT_CC_SHARED_LIBSCT_BINUTILS_PLUGINS=y.config
这就是它的配置方式（部分build.log）：

它会导致以下构建错误：
> liblto_plugin building gcc with plugin support requires a host that supports -fPIC, -shared, -ldl and -rdynamic.
它似乎有静态（不依赖于任何东西）和“带插件”听起来是相互排斥的。这是对的吗？
有没有办法不使用 lto_plugin 共享库而是静态地（并且仍然调用-flto）来构建它？
PS。我可以避免静态链接它，但我不希望它动态链接：
