Please note that both CONFIG_SPL_BUILD and CONFIG_TPL_BUILD
must be defined during the build of TPL image.

To sum up in a matrix, the definition of the these macros is like this:

                            CONFIG_SPL_BUILD    CONFIG_TPL_BUILD
non-SPL build:              undefined                  undefined
SPL build                      defined                      undefined
TPL build                      defined                      defined


Maybe do you think it looks weird? ( Me too.)
But the implementation has been like this
since TPL infrastructure was introduced by commit 3aa29de.

Defining only CONFIG_TPL_BUILD does not work.
