It looks like the -fPIC option uses the ebx register which GCC complains about. We can work around this by just using a different register, the
specific register of which I'm letting the compiler decide on. The "k" prefix is used to specify a 32-bit register. The {...} syntax is for
supporting different assembly dialects.
What's basically happening is that we're saving and restoring the ebx register manually.
