I'm afraid that your use case is currently not very well covered.

So we should probably add a proper hook for it. In the meantime, could
you give the following idea a try?

-----

ifneq ($(INSTALL_DIR),)
all: map
endif

map: $(TARGET)
	nm $< | sed "s/some/magic" > $@

-----

The check for 'INSTALL_DIR' is needed because the target.mk file is
actually visited twice during the build. First, it is examined to find
out the inter-library dependencies. This dependency stage is followed by
the actual build stage. The custom rule should be executed in the latter
stage only. As INSTALL_DIR is defined only at the build stage, we can
use it as a condition here.

The dependency from $(TARGET) ensures that your binary exists before
'nm' is called on it.

Cheers
Norman
