I successfully built the TF-A BL31 for the ZynqMP using this rule.

However, I saw that the TF-A build uses the current git commitish for
BUILD_STRING, which will be written into the binary. If I build the
TF-A with this rule, this ends up to be the commitish of the BSP. I'm
not sure if I actually want this, but I don't know what to put there
instead.
