Dynamic Shared Object.  This is a standard term.  It's not mentioned in
the ld manual; feel free to contribute a patch.

The hidden symbol `_Unwind_GetIP' is being referenced by a shared
library.  Figure out which one it is (I don't remember the reason why
we don't print that here; I believe it's pretty hard to recover from
our data structures at that point).  Then rebuild that library using
'gcc' to link and the symbol should no longer be undefined.

Google would have been happy to tell you that "DSO" and "shared
library" are basically synonyms.
