--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I don't really know why, not sure if GTY types simply must not appear in target
headers other than the main one or one needs to mark such headers somehow such
that gengtype is aware of those, but the generated gt-aarch64-builtins.h after
the change loses:

where the former is I believe what breaks the PCH.
