Are you sure? I would like to see this sent upstream: I expect they
will take it as we are not the only people who care about
deterministic builds.
That said, with "--with-libunwind" configure should fail if unwind is
not found. Your patch does not seem to do this -- see comment below

Configure will succeed if --with-libunwind is set but unwind is not
present: this should not happen. Something like this should work
correctly in both cases (please check that though: I wrote without
testing):
AC_ARG_WITH([libunwind],
AS_HELP_STRING([--without-libunwind], [Do not use libunwind]))
AS_IF([test "x$with_libunwind" != "xno"],
[PKG_CHECK_MODULES(LIBUNWIND,
[libunwind],
[have_libunwind=yes],
[have_libunwind=no])],
[have_libunwind=no])
AS_IF([test "x$have_libunwind" = "xyes"],
[AC_DEFINE(HAVE_LIBUNWIND, 1, [Have libunwind support])],
[AS_IF([test "x$with_libunwind" = "xyes"],
[AC_MSG_ERROR([libunwind requested but not found])])])
