support byacc in addition to bison

Browse source 
Use -b to explicitly set file prefix, so that byacc generates files with
the same names as bison.

Add %locations to dtc-parser.y to explicitly enable location tracking
for byacc, and define YYERROR_CALL to prevent byacc from defining it to
call yyerror with 2 parameters because of the locations directive,
because dtc-parser.y defines yyerror to accept one parameter.
