>From http://gcc.gnu.org/install/specific.html:
“out of memory” bootstrap failures may indicate a problem with process resource
limits (ulimit). Hard limits are configured in the /etc/security/limits system
configuration file.



Did you read that page and does changing the limits help?

out of memory allocating 16 bytes after a total of 4161654796 bytes

/etc/security/limits:
default:
        fsize = 2097151
        core = 2097151
        cpu = -1
        data = 262144
        rss = 65536
        stack = 65536
        nofiles = 2000

I had someone add memory to the machine and still : 
build/genattrtab ../../gcc/config/rs6000/rs6000.md > tmp-attrtab.c
out of memory allocating 16 bytes after a total of 4161654796 bytes
On a closer look that's 4161654796 =F80D-D00Ch 
I mean genattrtab is trying to allocate 4 gigs of mem
I think this is a bit too much for anything a compiler might want to do.
I suspect it's allocating storage in a loop

Fortunately I found the gcc binaries for my machine (as a matter of fact I used
gcc 4.1.1 to compile itself).

No, that is how much it allocated overall,  not how much is actually still in
use.

The 4G is the cumulative allocation, not the total amount of memory currently
in use.

The problem has nothing to do with physical memory installed in the system. 
The process data and stack resource limits need to be larger to compile GCC.
