I guess this should read:
(struct target_so_ops): New member lookup_lib_global_symbol.

And those file names have changed in the latest version:
* gdb.base/solib-symbol.exp: New file (testcase multiple symbol lookup).
* gdb.base/solib-symbol-lib.c: Likewise.
* gdb.base/solib-symbol-main.c: Likewise.
I've committed the patch with the above ChangeLog changes now.
Thanks,
