Indeed, this worked. Also, not sure what Adrian was doing wrong, but I
added -32 into sparc/cpugas.pas file as I said, and from then on I started
getting 32 bit object files, and after fixing the Makefile, I got a 32bit
FP executable, crosscompiled. Maybe something on the buildbox will reveal,
why it doesn't work there.

I'm crosscompiling from Darwin, using binutils 2.27, which I built as
sparc64-linux-gnu target.
