Specifying a debuginfo path independently of sysroot

[Ray Ruvinskiy <rruvinsk at sybase dot com>]

Hello,

I was wondering if it was possible to pass a custom debuginfo path  
from frysk to libdwfl without using the -sysroot switch. For example,  
suppose I have /my/path/to/program and its debug file is /my/path/ 
to/.debug/program. This works with gdb, and the callback documentation  
in libdwfl.h (line 242) suggests that libdwfl supports this idiom, as  
well.

If this is not currently possible, I was wondering if it might be  
desirable to allow for this. I wouldn't mind taking a crack at  
implementing this, if given an idea as to what semantics would be  
desired.

Thanks,

Ray
