m4: update to 1.4.21.
* Noteworthy changes in release 1.4.21 (2026-02-06) [stable]
** Fix the `eval' builtin to reject input like `0x' that C does not
accept as an integer literal, rather than silently treating it as zero
(present since "the beginning").
** Fix the `define' and `pushdef' builtins to always warn when attempting
to concatenate the result of using the `defn' macro on a builtin macro
with anything else. This is a counterpart to the change in m4 1.4.11
that issues a warning when `defn' with multiple arguments attempts to
perform concatenation. Attempting to use the output of `defn' anywhere
other than a lone argument during macro definition has never been
portable, but now the outcome is always the remaining text, rather
than being dependent on whether `defn' was used before or after the
other text (present since "the beginning").
** Port to glibc 2.43, which implements functions like strchr as macros
