I noticed a similar thing with how libkrb5 uses libcom_err.

I changed:

 libkrb5_la_LIBADD = \
-       ../com_err/error.lo ../com_err/com_err.lo \
+       $(LIB_com_err) \

Not so much because it caused any errors that I noticed, but this
change would be required if the multiple versions libcom_err that
exist were ever merged into one.

My immediate questions is:

why does libeditline.a contain vasprintf?  (it should be able to use
the version in libroken.)

If a grep the editline source code for "vasprintf" I don't find any
matches (Heimdal 0.3d), except a macro definition which doesn't seem
to be used anywhere:

roken_rename.h:#define vasprintf _editline_vasprintf
