You didn't say what GDB version you are using.  Apparently, it is too
old.

That's unlikely to be right.  solib-search-path should be a directory
containing libraries (if you need to use it at all, which you rarely
do).  solib-absolute-prefix should be a filesystem image, so a
directory containing "lib" and "usr".

This is probably related to the solib-absolute-prefix problem.
