Minor patch for AIX & HP-UX (0713)

[rbrown64 at csc dot com dot au]

The following corrects one compilation error for infttrace.c
on hppa1.1-hp-hpux11.00, and provides a stub no_shared_libraries
for remote.c on HPUX and AIX 4.20. AIX also needed LDFLAGS=-Wl,-bbigtoc
to link gdb successfully.

My corporate assignment is in doubt if the no_shared_libraries stubs
don't count as a minor change. (Yanked directly from solib.c).

2001-07-16  Rodney Brown  <rbrown64@csc.com.au>

     * infttrace.c (child_thread_alive): Fix gdb_tid typo.
     * somsolib.c (no_shared_libraries): Provide stub.
     * xcoffsolib.c (no_shared_libraries): Provide stub.
