Silence Bison deprecation warnings
Bison >=3.0 issues warnings about
%name-prefix="base_yy"
instead of the now preferred
%name-prefix "base_yy"
but the latter doesn't work with Bison 2.3 or less. So for now we
silence the deprecation warnings.
Back-patch to 9.2 and 9.3 -- the newer branches already have this fix.
