gcc-plugins: test plugin support in Kconfig and clean up Makefile
Run scripts/gcc-plugin.sh from Kconfig so that users can enable
GCC_PLUGINS only when the compiler supports building plugins.
Kconfig defines a new symbol, PLUGIN_HOSTCC. This will contain
the compiler (g++ or gcc) used for building plugins, or empty
if the plugin can not be supported at all.
This allows us to remove all ugly testing in Makefile.gcc-plugins.
