Cannot use CONFIG_GCC_PLUGINS: your gcc installation does not support plugins, perhaps the necessary headers are missing?

I manually fixed up the gcc header files to include the ones with the
definition for now, to address those, but I don't know if that change is
What was needed?
I added '#include "memmodel.h"' and '#include "tree-vrp.h"', respectively, to
the headers that failed to get compiled.
This might be the correct solution, or the headers might not be meant to
be used standalone and instead require being included in the right order.
Gcc commit svn+ssh://gcc.gnu.org/svn/gcc/trunk@239638 moved
value_range_type from tree-ssanames.h to tree-vrp.h, I've added
Kugan to Cc, maybe he can clarify what that means for plugins.
