commit: https://git.buildroot.net/buildroot/commit/?id=e068f33700d63c4a89329fe3f168ae249544877c branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master Some packages requires support on the build machine to create gcc plugins. This commit adds a blind option, BR2_NEEDS_HOST_GCC_PLUGIN_SUPPORT, which such packages can select. When this option is enabled, the logic in support/dependencies verifies that everything needed on the build machine to build gcc plugins is available.
