Porting SAPDB to ppc64 Linux

Hi,

I am interested in porting to ppc64/Linux. Since it already runs on
Linux and ppc64/AIX it shouldnt be too hard.

I had a quick look and for AIX we have:

host_cpu = _IBMR2
host_os = AIX

and for Linux we have:

host_cpu = _IBMR2
host_os = LINUX

Id prefer POWERPC to _IBMR2 but thats not too important :)
Unfortunately the source uses _IBMR2 when it should be using AIX:

#if defined(_IBMR2) || defined(SUN) || defined(HPUX)
extern int    sys_nerr;
extern char * sys_errlist[];
#endif /* _IBMR2 || SUN || HPUX */

This has nothing to do with the host_cpu and everything to do with the
host_os. Thoughts on changing all these ifdefs to use AIX not _IBMR2?
