Please run `make oldconfig' after modifying the config (e.g. by copying it from
Config.amiga).

floppy_hardint() is a routine from the PC-style floppy driver. Probably it was
enabled before you copied Config.amiga.

Hence try this:
    make oldconfig
    make dep
    make clean
    make zImage modules
