newppc-branch: Some problems

[Franz Sirl]

Hi,

currently on powerpc-linux-gnu I cannot bootstrap unless I start the 
bootstrap with 'make bootstrap CXXFLAGS="-O2 -g -fno-inline"'. Without the 
-fno-inline the bootstrap fails with:

   /home/fsirl/obj/gccm/gcc/g++ -B/home/fsirl/obj/gccm/gcc/ 
-B/home/fsirl/gnubin/ppc-redhat-linux/bin/ -c -g -O2 -fvtable-th

There's definitely something fishy going on with the tree-based inlining on 
PPC, as I already had problems with it in the normal branch. Clinton looked 
a little bit at this problem, maybe he already knows more about it.

The other problem is this warning:

It happens quite often during bootstrap and also invalidates some testcases.
