bison: rely on bison's %require to check a version requirement See https://lists.gnu.org/archive/html/bug-gnulib/2020-05/msg00021.html. * m4/bison.m4 (gl_PROG_BISON): Let bison itself decide if it it recent enough of not. So far it is the only know Yacc tool that supports '%require'. Other yaccs will actually even choke on seeing the -o option after the input file name. * m4/parse-datetime.m4: Simplify gl_PROG_BISON invocation.
