In the ELF binary obviously I can't use anything that's os specific (file access for example). Or can I if I link to dynamic libc? The only possibility in this case is to embedde binary data into executable and process it by the executable. In this case I can't verify the output (unless I embed expected output also)

I don't really understand what you are trying to do or why you are using
ELF at all.  Why not just compile your code into PE format in the first
place?

The only realistic way that you can create a PE DLL is to compile code
with a PE compiler.  Otherwise you aren't going to get the right code
sequences and relocations.  It is theoretically possible to pursue other
paths but they are all going to be complex and difficult.
