$NetBSD: patch-src_Makefile.in,v 1.1 2025/01/24 09:20:37 riastradh Exp $

Don't delete $GRAM.tab.h files created by bison.  Older versions of
Bison copied the $GRAM.tab.h files verbatim into the $GRAM.tab.c files,
but versions of Bison since 3.6 instead use #include "$GRAM.tab.h",
which requires us not to delete the .tab.h file.
