That is effectively what I have done,  and it does fix it.  My version
looked like:

	#define weak_alias(name, aliasname) \
		asm(".global " #name ";.weak " #aliasname ";" #aliasname "=" #name ";");

Seems to have done the right thing.  Full build of the tools completed.

I also want to define __BEGIN_DECLS and __END_DECLS for the C++ libs.
Is there a reason we don't do this.  We could make it an option ?
You cannot use link against uClibc with C++ unless these are set
appropriately,  you get lots of unresolved symbols,

Cheers,
