jtc 9540190d45 This file, which will be included by <sys/cdefs.h>, will contain macros
such as __warn_references() and __weak_reference() which are actually
machine dependant.  This will make it easier for ports that are being
bootstraped with ELF and ECOFF based toolchains.

This change also introduces a new macro, _C_LABEL(x).  _C_LABEL expands
its argument, an identifier, to a character string of the identifier
name as it is represented in an object file.

For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports
_C_LABEL(x) will expand to "x".
