I did some testing with a cross-compiler myself and I don't think
there is a general solution to this problem. It's not one particular
file that is causing the problem but seemingly the sheer size of the
resulting vmlinux file - even though the toal vmlinux.o size is
"merely" up about 100MiB (from around 1,03Gib to 1,13Gib).

I think I'll need help from people with knowledge of the powerpc
toolchain here.
