Hmm, we're rapidly accumulating a long list of ways to alter the 
absolute-prefix. cf also:

(gdb) help set debug-file-directory
Set the directory where separate debug symbols are searched for.
Separate debug symbols are first searched for in the same
directory as the binary, then in the `.debug' subdirectory,
and lastly at the path of the directory of the binary with
the global debug-file directory prepended

and the ./configure option:

   --with-sysroot[=DIR] Search for usr/lib et al within DIR.

Might be time for some consolidation:

set absolute-prefix {source,solib,sysroot,debug,all} <path>

(although an immediate source-absolute-prefix shouldn't hurt).

BTW, wasn't there a mechanism for editing/replacing part of the source 
prefix added, or did that get lost?
