rockboxdev: fix glib compile error on hosts with Python 3.12 (FS#13471)

On hosts running Python 3.12, building the hosted MIPS toolchain fails
on glib with the error

    Traceback (most recent call last):
      File "<string>", line 2, in <module>
    ModuleNotFoundError: No module named 'imp'
    gmake[6]: *** [Makefile:982: install-codegenPYTHON] Error 1
    gmake[6]: Leaving directory '/tmp/rbdev-build/build-glib-2.46.2/gio/gdbus-2.0/codegen'

due to 'imp' being removed from Python 3.12 after a long deprecation
period. The module is imported by automake's py-compile script, but
in newer versions of automake this has been updated to use 'importlib'
instead, so running autoreconf fixes this.

We need to patch m4macros/glib-gettext.m4 to avoid an error running
autoreconf (see: https://gitlab.gnome.org/GNOME/glib/-/issues/1159):

    ac-wrapper: autoreconf: warning: auto-detected versions not found ( 2.69 2.69); falling back to latest available
    autoreconf-2.71: export WARNINGS=
    autoreconf-2.71: Entering directory '.'
    autoreconf-2.71: configure.ac: not using Gettext
    autoreconf-2.71: running: aclocal --force -I m4macros ${ACLOCAL_FLAGS}
    am-wrapper: aclocal: warning: auto-detected versions not found (1.15); falling back to latest available
    m4macros/glib-gettext.m4:39: error: m4_copy: won't overwrite defined macro: glib_DEFUN
    m4macros/glib-gettext.m4:39: the top level
    autom4te-2.71: error: /usr/bin/m4 failed with exit status: 1
    aclocal-1.16: error: /usr/bin/autom4te-2.71 failed with exit status: 1
    autoreconf-2.71: error: aclocal failed with exit status: 1

This problem goes away in glib 2.47.5 when they switched to using
upstream gettext.
