Patch review request for Bug 2664 - unexpected declaration-only types

[Dodji Seketeli]

Hello Giuliano, Matthias and whoever would be interested in reviewing
some patches :-)

These two small patches that follow this message are meant to fix the
problem reported at
https://sourceware.org/bugzilla/show_bug.cgi?id=26646.

The first one is a pre-requisite to fix a crash caused by the fact
that we hit an assert in the symtab reader.

The second one should hopefully fix the actual problem reported.

Could you please review the patches and test them in your environment
to see if they are useful at all?

Thanks!
