If we can spit out {spl_,tpl_,}autoconf.h files that might help a bit.
But would it help with the recent case of SPL has SATA+AHCI+!PCI while
full U-Boot has SATA+AHCI+!PCI AND SATA+AHCI+PCI ? Today we can't
support the SPL case without adding the handful of SPL_xxx symbols so
that we can say we have SATA+AHCI without PCI.
