You're right, of course: I'd mostly forgotten about the include
flattening.
I've now installed the patch below as obvious after successful
sparc-sun-solaris2.11 and i386-pc-solaris2.11 bootstraps.
However, this seems extremely fragile to me: neither Jakub nor yourself
remembered about this requirement and it affects only a few platforms.
Feels like an incomplete transition...
