Should they though? If there's no SPL, surely we still want to generate
the same output filenames, so that consumers of the binaries don't have
to care whether a particular board needs the SPL tacked onto the binary.

In other words, rather than:

u-boot-nodtb-tegra.bin == SPL + U-Boot
u-boot-dtb-tegra.bin == SPL + U-Boot + DTB

... when SPL is disabled, shouldn't we generate:

u-boot-nodtb-tegra.bin == U-Boot
u-boot-dtb-tegra.bin == U-Boot + DTB

That would require modifying the rules that generate those files not to
include the SPL binary in the concatenation, rather than simply not
generating those files at all.
