You'll need the latest version of binutils since -shared is a command
for the linker.  Though updating GCC cannot harm if you use an older
version.

gcc -o khook.o -c khook.o
gcc -shared -o mydll.dll khook.o

Other files for your DLL if you want to include others too.

dlltool is deprecated, you don't need it, its all done by GCC and the
linker.
