support/dependencies: add BR2_NEEDS_HOST_GCC_PLUGIN_SUPPORT

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.
