Yes, it is in <build directory>/gcc/auto-host.h:
/* Define 0/1 if your assembler and linker support COMDAT groups. */
#ifndef USED_FOR_TARGET
#define HAVE_COMDAT_GROUP 0
#endif

So, I guess either this file is not included in gcc/varasm.c or the 
USED_FOR_TARGET macro is defined.  Gonna check this now...
