[Buildroot] [PATCH v2 1/6] boot/at91bootstrap3: bump 3.x series to 3.10.4

[Angelo Compagnucci <angelo.compagnucci@gmail.com>]

The patch fixing the build with GCC 15 is not upstream in 3.10.4 yet
and applies as is: copy it to the v3.10.4 directory. The v3.10.3 copy
stays, used by the defconfigs that fetch v3.10.3 from git
(acmesystems_acqua_a5_* and at91sam9x5ek_*).

+Subject: [PATCH] include/types.h: conditionally define bool, false and true
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+include/types.h typedefs ‘bool’ and macro-defines ‘false’ and ‘true’.
+However, since C23, these are predefine keywords. As C23 is the default
+C dialect for GCC 15, building with this compiler fails with:
+
+    include/types.h:23:23: error: ‘bool’ cannot be defined via ‘typedef’
+       23 | typedef unsigned char bool;
+          |                       ^~~~
+    include/types.h:23:23: note: ‘bool’ is a keyword with ‘-std=c23’ onwards
+
+Fix this build failure by only defining ‘bool’, ‘false’ and ‘true’ on C
+dialects older than C23.
