The problem is that the newer compiler is defaulting to -fpie, so &code16_func1 
is not a constant.

Need to add -fno-pie to compile this.  Which of course adds the confusion of 
old compilers that don't support that.  We have CFLAGS_NOPIE in configure, but 
that doesn't directly help cross-compile.
