Selecting this option will pass "-Map=$(TOPDIR)$(DELIM)nuttx.map" to ld
when linking NuttX ELF. That file can be useful for verifying
and debugging magic section games, and for seeing which
pieces of code get eliminated with DEBUG_OPT_UNUSED_SECTIONS.

## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.
This PR cleans up the logic so they're only listed once.
## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!
## Testing
CI will test all build
This reverts commit 45672c269d.
Because:
* It's very confusing to have cc as LD.
* I don't see what "-nostartfiles -nodefaultlibs" in LDFLAGS are
supposed to do when we use LD directly. It would be simpler to
remove them from our LDFLAGS.
