nm *is* the right tool, but only for file types it knows about.

You should only expect a platform’s native nm to support the native executable types of the platform it runs on.  In the case of Cygwin, that’s various flavors of COFF and PE.  OMF is an entirely different format.

Cygwin’s nm happens to also support ELF for some reason, but that is yet a third object format.

Assuming libbfd knows OMF, you could rebuild your own OMF cross-development toolchain.  Then *its* nm would be the right tool for the job.
