Let me ask again:  Why do you want to use CONFIG_BUILD_ELF64=y ?

If your board use CKSEG0 load address, I can not see any point setting
CONFIG_BUILD_ELF64=y.  I think the description in Kconfig (and the
name of CONFIG_BUILD_ELF64 itself) should be changed to make people
enable it only if really needed.  And it is already done by Franck's
pending patchset.
