Good to see that it now works.

Just looked at dxe3gen documentation, and it says:

Usage: dxe3gen [-o output.dxe] [options] [object-files] [ld-options]
   or: dxe3gen -1 output.dxe symbol input.o [input2.o ... -lgcc -lc]

that 'ld-options' is always at the end which includes any link libs.
So, the order of arguments _is_ important.

The thing is, dxe3gen invokes ld, not gcc.  gcc is a front-end to ld
and handles any such ugliness behind the scene and doing the same for
dxe3gen might be a real pain.

If someone other than me can generate solution for this, or at least
some documentation, it'd be nice.
