IMO, PLAIN_VERSION isn't descriptive enough (should really be called
VERSION..?).  How about going with something like:

#define U_BOOT_STR "U-Boot"
#define U_BOOT_VERSION U_BOOT_STR " %s%s"...

and then

&U_BOOT_VERSION[sizeof(U_BOOT_STR)]

(the - 1 is not necessary since we want to include the ' ')

this maintains consistency and the fact that the mkimage version is
directly tied to it's parent project, U-Boot's, version number.
