no, does not help, as -lgmp is already passed to gcc by ghc:


        /usr/bin/gcc -fno-stack-protector -DTABLES_NEXT_TO_CODE -o
        linker_unload linker_unload.o

        -Wl,--reduce-memory-overheads
        
but due to --no-needed, and linker_unload indeed not requiring any
symbols from gmp, the linker does not link it.
