This patch makes it look like we would compile mmu_helper.c after all. Is that 
it? That looks like the simplest solution (ifdef'ing away all helpers) but I 
thought mmu_helper was supposed to have all TCG-only code relating to MMU.

Yes, we will always compile mmu_helper.c. -- it was always going to have the 
stuff for gdbstub.

It was exc_helper which I was hoping for tcg-only (but then we decided that 
ifdefs were going to be the short-term solution).
