Silence -Wunused-but-set-variable error with clang
When building with clang-15, I get:
CXX libctf_parser_la-parser.lo
parser.cpp:2920:9: error: variable 'yynerrs' set but not used [-Werror,-Wunused-but-set-variable]
int yynerrs;
^
This is because it warns for something like this:
int n;
n = 0;
++n;
whereas previous versions do not.
This is generated code, so there's not much more we can do other than
silence the warning for the file.
