These, in fact, are used.  Every "option ..." line in the config file
generates a -D... uses during the kernel build.

If you want to alter the options you pass to the compiler, use:

makeoptions     COPTS="-O2 -m68030"

You should not remove -msoft-fload ... This is used quite specifically
to keep the compiler from emitting floting point instructions.  This
reduces the chance for floating point exception or inconsistent FPU
state while executing kernel code.  (The kernel should never use floating
point unless _explicitly_ told to do so, in assembly language.)

I'll let amiga guys answer your other questions :-)
