On AIX, when runtime linking is active, undefined symbols are allowd by
default. Additionally, the '-G' linker flag needs to be specified before
the '-bernotok' and any other user-defined linker flag, or '-G' would
override some of them again.
* m4/libtool.m4: (no_undefined_flag) Define for AIX runtime linking.
(allow_undefined_flag) Undefine for AIX runtime linking.
(archive_expsym_cmds) Reorder to have -G before $no_undefined_flag.
