Yecchhh....  Just how many of those pre-includes do you want to add?
Seriously, if we get enough of those, it might make more sense to take
them into a separate directory and add it to search paths, including
that for userland objects of uml.  If not, I'd rather copy them to
include/generated in arch/um/Makefile and explicitly #include <generated/foo.h>
them from user.h.  It's trivially doable and as long as we have relatively
few of those guys it's less PITA...
