yes, this helped. Still I see a failure in cofigure before stage3 starts:
checking for powerpc-suse-linux-gcc...
/home/victork/mainline/build.trunk.127373/./prev-gcc/xgcc
-B/home/victork/mainline/build.trunk.127373/./prev-gcc/
-B/home/victork/mainline/usr.trunk.127373/powerpc-suse-linux/bin/
checking for C compiler default output file name... a.out
checking whether the C compiler works... configure: error: cannot run C
compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.
Seemingly, the compiler created by stage 2 is unusable. I'm not sure if it was
originally a good idea to try to bootstrap ppc32 compiler on ppc64 machine. Do
you think it is feasible? What should be configuration and bootstrap make
flags?
