Commit e320a76db4b0 ("powerpc/cputable: Split cpu_specs[] out of cputable.h")
moved the cpu_specs to separate header files. Previously PPC_FEATURE_BOOKE
was enabled by CONFIG_PPC_BOOK3E_64. The definition in cpu_specs_e500mc.h
for PPC64 no longer enables PPC_FEATURE_BOOKE.
This breaks user space reading the ELF hwcaps and expect PPC_FEATURE_BOOKE.
Debugging an application with gdb is no longer working on e5500/e6500
because the 64-bit detection relies on PPC_FEATURE_BOOKE for Book-E.
