What does objdump -h say for one of those Red Hat debug files?  Is there
a .text section and/or a section marked loadable?  I mean, I suppose we
could stick a dummy .text section in the .dbg file if it will shut up
gdb, but that sounds just as hacky as teaching gdb to properly suppress
its warnings.  I went over symfile.c:syms_from_objfile() again and all I
can really conclude is that if gdb doesn't warn when loading a Red Hat
debug file (which obviously it doesn't), then one of the following must
be true:

- it's being loaded with some other completely different mechanism
elsewhere (doesn't seem likely as the .gnu_debuglink code is right
there)
- the linux debug file has a .text section
- the linux port successfully supresses the warnings from being
displayed in all cases
