If I see that certain externals are referenced, then I know I need to 
generate a stub
for them.

Most of this I take care of in an IR pass but some I can't know about 
because they
are just standard libc type functions. There are only a few that create 
this problem for mips16 hard float
when it is linked as c++.

I intend though to move all the earlier actual machine code generation 
from the IR pass to this
same place that I am using to solve the problem at hand.
