Avoid crash with Ada and -fdata-sections

A user noticed that gdb would crash when showing a backtrace.
Investigation showed this to be a crash in the DWARF reader when
handling a "pragma export" symbol.  The bug here is that earlier code
decides to eliminate the symbol, but the export code tries to add it
anyway -- but to a NULL list.
