Switch to the new kernel config rendering infrastructure. Remove the
"IA32 a.out support" which is already removed and was completely useless
for multilib even before the removal. Mention the new "IA32 emulation
disabled by default" option. Separate mx32 and m32 kernel
configuration. Fix the consequences building a multilib when lacking
the corresponding kernel feature.
The incompatibilty between systemd and CONFIG_AUDIT has been fixed since
Linux kernel 3.14, thus there is no reason to disable it on LFS. And we
are referring to pam_loginuid.so from /etc/pam.d in BLFS, which is
completely useless if CONFIG_AUDIT is disabled.

In Linux 6.6 DRM_FBDEV_EMULATION no longer depends on FB, so we no
longer need to select FB (tested in a QEMU VM).
But if DRM is selected, we must select both DRM_FBDEV_EMULATION and
FRAMEBUFFER_CONSOLE or we'll see only blank screen. And now
FRAMEBUFFER_CONSOLE is not selected by default, be warned!!
Import kernel-config infrastructure from BLFS and use it for kernel
configuration. Note that kernel-config.py is slightly different from
BLFS: we need role="nodump" for <screen> here.
