gdb not detecting function sections correctly for functions in overlays

[Arnab Bhaduri]

Tensilica has previously provided code (I forgot to mention that I'm working on the Tensilica Xtensa, which is now part of Cadence). I haven't been working on this for long and still haven't figured out how to deal with this stuff inside Cadence, so it might take a little while. I'll need to figure that out before I send you any patches. I can certainly file a bug.

Thanks
Arnab
