Thanks! Attached are the two patches I will commit momentarily.
The first one implements the suggestion you sent on IRC. The second
is about renaming the name of the XML element.
gdb/ChangeLog:
* target.h (enum target_object) [TARGET_OBJECT_LIBRARIES_AIX]:
Renames TARGET_OBJECT_AIX_LIBRARIES.
* rs6000-nat.c: Replace TARGET_OBJECT_AIX_LIBRARIES with
TARGET_OBJECT_LIBRARIES_AIX throughout.
* solib-aix.c: Likwise.
gdb/ChangeLog:
* features/library-list-aix.dtd: Replace library-list by
library-list-aix.
* rs6000-nat.c: Replace library-list by library-list-aix
throughout.
* solib-aix.c: Likewise.
Tested on ppc-aix.

Subject: [PATCH 2/2] AIX: Change XML to use library-list-aix instead of library-list.
This is more consistent with what we do with other similar XML lists,
and avoids a potential confusion with the library-list XML list.
gdb/ChangeLog:
* features/library-list-aix.dtd: Replace library-list by
library-list-aix.
* rs6000-nat.c: Replace library-list by library-list-aix
throughout.
* solib-aix.c: Likewise.
