I objected to a previous patch version using the weak attribute and 
thought that a way was found at that point to do without it.  There's no 
way it should be needed on the host for anything reasonable in GCC - I 
don't know what this port is trying to do but there's bound to be a better 
way.  Split up objects as necessary and ensure that exactly one 
implementation of each function needed is linked into each compiler.  If 
the problem is generic functions calling C-family ones, use function 
pointers initialized at an appropriate point.  (REGISTER_TARGET_PRAGMAS is 
abused by ARM as a "C family initialization hook" though a separate hook 
would be better.)
