Some of them can; notably the binutils ld, which comes from the same source as and uses the same mechanism as objcopy.

they do? I couldn’t any flag in that direction. I just tried a few combinations with a simple testprogram (git repo attached, every commit is one state). Unfortunately, using dlopen does not not help if some other shared library loads gmp regularly; there is still only one global state. And statically linking gmp into the share object does not work, as Simon predicted, because the static gmp library is not compiled with PIC. The promising ld option "-Bgroup" does not seem to have the desired effect. If only dlopen had RTDL_PRIVATE support...
