[ Beware, the answer might not be the obvious ]

But unfortunately, it is.  After reverting the varasm change from the 
patch, I was able to get past the problem spot, caused by a

	.section	.sdata, "aws"

statement.  The powerpc-unknown-linux-gnu GAS apparently doesn't like 
the "s" in the section attributes (this is
as --version
GNU assembler 2.15

so it is pretty old - Debian testing as of last weekend).

In short, Jan Beulich's update to varasm.c is probably correct, so I 
only reverted it locally.
