GNU patch configure seems a bit odd with regards to bison :
checking for bison... bison
checking for bison 2.4 or newer... 3.8.2, bad
Well that is weird.

So "bad" is a bit strange there.
Could it be that you have the environment variable POSIXLY_CORRECT set?
darn it
If so, this was fixed in Gnulib on 2025-05-11, after the latest GNU patch
release.
If not, then what is the result of executing
$ cat >conftest.y <<_ACEOF
%require "2.4"
%%
exp:
_ACEOF
$ bison conftest.y -o conftest.c
centauri# unset POSIXLY_CORRECT
centauri# bison conftest.y -o conftest.c
centauri# echo $?
0

well that solves that.
checking for bison... bison
checking for bison 2.4 or newer... 3.8.2, ok
yup.
