On the PA under hpux, undefined external symbols need to
be "imported" to set the type of the symbol.  If this isn't
done, the dynamic loader won't be able to resolve the
address of the symbol correctly.  The HP SOM linker is
also known to dump core if a P fixup occurs for a data
symbol that should be a function symbol.

The GNU assembler doesn't treat the above as an error but the executable may malfunction in a subtle way.  Thus, this needs to be fixed for correct operation with the GNU assembler as well.

This appears to be a regression from 3.0.2 where we had
similar problems with typeinfo nodes in the regression fix phase.
