It a stupid dependency on a generated file.
The file only gets generated upon a successfull 'make modules', whereas
genksyms is used for every file compiled as a module.
The workaround is to do:
disable CONFIG_MODVERSIONS
make modules
enable CONFIG_MODVERSIONS
make
We could eventually fetch definition from <asm/module.h> but that seems
to drag all other stuff in.
So fix is instead to hardcode the check for the two relevant
architectures direct in genksyms.
Is genksyms used outside the kernel?
