yes. if you look at the gcc-configure-cross.inc then it disables
optspace for SPE targets. thats why it works for gnuspe but when I
did that I only saw the problem on gnuspe and wanted to keep the 
effect minimal. But it seems now we need this ppc wide thats why
the new patch. 

Although using -Os in kernel might cause the same problem even if we
sort out libgcc because kernel does not use libgcc and I dont know if
it implements these functions.

If this causes the issue then we have to do same fix for kernel where
we compile kernel with -O2 and not with -Os
