What I was using in my earlier experiments was "Ubuntu 4.4.3-4ubuntu5.1" on
x86_64-linux-gnu native. But I happen to have handy a GCC trunk from last
week sometime built for --target=arm-linux-gnueabi:
$ ./xgcc -B./ -E -dM -std=c99 -x assembler-with-cpp /dev/null | grep '#define [^_]'
#define unix 1
#define linux 1
