Browsing buildroot elf2flt sources, the most obvious thing to do is to 
modify the linker script to explicitly manage the phdrs:

  PHDRS {
    text PT_LOAD ;
    data PT_LOAD ;
  }

I guess I can assume you've tried this already and there are other problems?

No.

But personally think it's a shame not to be able to easily generate any 
appropriate relocation with data directives.  No telling how they'll be 
useful for random applications.  Of course, you can always do something 
gross like

	.reloc	., R_68K_GOT32O, foo
	.long	0

but... really...  ;-)
