    [gdb/build] Work around GCC ipa-modref bug

    PR mi/32571 reports the following problem:
    ...
    $ gdb -q -batch -ex "b bla.c:100"
    <random output>
    Make breakpoint pending on future shared library load? (y or [n]) \
      [answered N; input not from terminal]
    ...
    while this is expected:
    ...
    $ gdb -q -batch -ex "b bla.c:100"
    No symbol table is loaded.  Use the "file" command.
    Make breakpoint pending on future shared library load? (y or [n]) \
      [answered N; input not from terminal]
    ...

    A few factors in reproducing this are building gdb using gcc 14,
    "-O2 -flto=auto" and --disable-nls.  For more details, see the PR.

    This turns out to be caused by a GCC PR [1], more specifically a problem in
    ipa-modref.

    Work around this by disabling ipa-modref for GCC versions 12-15 and 16.0,
    assuming the GCC 16.1 release will contain a fix.

    Tested on aarch64-linux and x86_64-linux.
