 ../../src/gdb/d-exp.y:762: multiple definition of `yydefred'
 ada-exp.o:/home/palves/gdb/build/gdb/ada-lex.c:925: first defined here
 ld: Warning: size of symbol `yydefred' changed from 464 in ada-exp.o to 336 in d-exp.o
 Makefile:1404: recipe for target 'gdb' failed

NetBSD's yacc uses a "yydefred" symbol that we missed renaming in the
Ada parser.  All other gdb parsers do this already.
