Since you seem to be following the same path as I did on ARM, I may as well ask: did you try removing -fPIC and -msingle-pic-base from compile options and adding -pie to the link options instead? Link option -pie generates ELF relocation and, on ARM at least, does a better job than GOT reloc, which does not fix handle pointers in initialized data while ELF reloc fixes them. And since ELF reloc does not modify code (it is a linker option), you end up with the same size for text+data+rodata. You do have a bigger FLASH image though, because the ELF reloc tables are bigger than the GOT table; but you can git rid of them / not copy them to RAM once relocated. The move from -fPIC to ELF on ARM can be looked for in the elf_reloc branch of the u-boot-arm repo.
