That's going to break tools other than the linker. Ian mentioned
VxWorks - the VxWorks loader doesn't understand ELF, it understands
the very limited subset of ELF that it has historically had to cope
with (the historical output of GCC/GAS/ld -r) and blows chunks if
handed anything else.
It seems to me that the Right Thing is to make ld -r on PowerPC64
not merge TOC sections when this would cause overflow. Final link
can do this, so I don't see why ld -r can't.
