* configure.in, configure: Recognize rs6000-*-aix4*.
	* config/powerpc/xm-aix.h: Reduce to include "xm-aix4.h".
	* config/rs6000/aix4.mh (XM_FILE): Point to xm-aix4.h.
	* config/rs6000/xm-aix4.h: New file.
	* config/xm-aix4.h: New file.

 From the Mentor work...enable configure & build on rs6000-ibm-aix4.1.*.
Note this is an unbelievably buggy debugger on this host.

/* The following text is taken from config/rs6000.mh:
* # The IBM version of /usr/include/rpc/rpc.h has a bug -- it says
* # `extern fd_set svc_fdset;' without ever defining the type fd_set.
* # Unfortunately this occurs in the vx-share code, which is not configured
* # like the rest of GDB (e.g. it doesn't include "defs.h").
* # We circumvent this bug by #define-ing fd_set here, but undefining it in
* # the xm-rs6000.h file before ordinary modules try to use it. FIXME, IBM!
* MH_CFLAGS='-Dfd_set=int'
* So, here we do the undefine...which has to occur before we include
* <sys/select.h> below.
