This removes symbols, not keeps them.
You want the linker flag: ``--no-gc-sections``
"Enable garbage collection of unused input sections. It is
ignored on targets that do not support this option. The default
behaviour (of not performing this garbage collection) can be
restored by specifying ‘--no-gc-sections’ on the command line.
Note that garbage collection for COFF and PE format targets is
supported, but the implementation is currently considered to be
experimental."

I need remove symbol, since the problem is some symbol from
importC reference to undefined symbol(need to be implement in d,
but they will never used).
after remove the unused symbol, I don't need to add the
implement all of them.
