I think ASM_OUTPUT_CONSTRUCTOR can be that macro, if we change the
documentation; it looks like the aoutos.h version was the only one that
would break with HJ's patch.  All the definitions for COFF and such
targets looked fine; they also rely on the value of the symbol within the
translation unit rather than having it available to the linker.  We only
need the symbols to be public if we're using collect.

Having another macro would also be fine, and would allow for runtime
selection.
