Don't forget to define REAL_ARITHMETIC in the gcc/Makefile, e.g.:
CFLAGS = -DREAL_ARITHMETIC
This forces GCC to software-simulate VAX floats so it can output the correct
bit patterns for VAX assembly.
Normally GCC has a grody assumption that all targets use the same float
format as the host, which these days is almost always IEEE, so it gets
away with it.
But cross-compiling to VAX breaks this immediately...
