It it possible to split the object file? Just move some functions to their
own implementation file, and link those together. There might be less
automagical inlining, but overall difference in performance should be
negligible, and a single object's size should decrease significantly. The
linker should be able to cope with GBs of total object size if it's 64-bit
and the final output file isn't too big.
It seems you are running into a binutils "as" implementation limit.
