The linux kernel is not reproducible because the build user
and domain is included into the kernel. Set the build user
to `builder` and build domain to buildhost.
It's also possible to build reproducible builds by setting
KERNEL_BUILD_USER KERNEL_BUILD_DOMAIN to static values.

As we're now going to pad all images by default, lets decrease the

It's being used only in x86 target to produce combined images, where
it's mandatory to have padded images in order to produce working
squashfs combined images usable in QEMU.
Currently we're producing unusable x86 combined squashfs images
(18.06.1, 18.06.2 and snapshots) as we don't enable TARGET_IMAGES_PAD,
thus providing very small space for the overlay filesystem, leading to
the following with OpenWrt 18.06.1 r7258-5eb055306f images on x86 QEMU:
root@(none):/# mount | egrep 'root|overlay'
/dev/root on /rom type squashfs
/dev/loop0 on /overlay type ext4
overlayfs:/overlay on / type overlay
root@(none):/# df -h | egrep 'root|overlay|Size'
Filesystem Size Used Available Use% Mounted on
/dev/root 2.5M 2.5M 0 100% /rom
/dev/loop0 113.0K 8.0K 97.0K 8% /overlay
overlayfs:/overlay 113.0K 8.0K 97.0K 8% /
So we should rather ensure proper image padding in image generation code
and we shouldn't rely on config options in order to generate usable
images.

Commit eae6cac6a3 ("lantiq: add support for AVM FRITZ!Box 7362 SL"), but
one needs an initramfs image to flash OpenWrt from stock firmware (as
described in the commit log). This patch has the initramfs image built
by default.
Thanks to blogic (for pointing to the FEATURES declaration in the target
Makefiles) and Musashino on the forum for suggesting
config/Config-images.in needed editing too. While at it, reorder the
TARGET_INITRAMFS_COMPRESSION_LZMA declarations alphabetically.
This patch will result in initramfs images for all lantiq subtargets
that have the ramdisk flag set. I tested on the falcon and ase
subtargets, which lack that flag, to confirm they don't produce any
initramfs images with this patch - which they do not.
Given the limited scope of the lantiq (sub)target(s), blogic indicated
this should be OK.

When CGROUP block io is enabled a new symbol is exposed and needs to
be set or unset else kernel oldconfig hangs waiting for input during
normal OpenWrt builds. Therefore add sane defaults for this symbol
in that case. Also, the defaults brcm2708 are different than generic
defaults because the platform's defconfig enables BLK_DEV_THROTTLING

upstream's kernel, not in OpenWrt config-4.xx).

Add a new config option to allow to select the default compile
optimization level for the kernel.
Select the optimization for size by default if the small_flash feature is
set. Otherwise "Optimize for performance" is set.
Add the small_flash feature flag to all (sub)targets which had the
optimization for size in their default kernel config.
Remove CC_OPTIMIZE_FOR_* symbols from all kernel configs to apply the new
setting.
Exceptions to the above are:
- lantiq, where the optimization for size is only required for the
xway_legacy subtarget but was set for the whole target
- mediatek, ramips/mt7620 & ramips/mt76x8 where boards should have
plenty of space and an optimization for size doesn't make much sense
- rb532, which has 128MByte flash

Configure variable SSP_SUPPORT is ambiguous for packages (tor, openssh,
avahi, freeswitch). It means 'toolchain supporting SSP', but for toolchain
and depends it means 'build gcc with libssp'.
Musl no longer uses libssp (1877bc9d8f), it has internal support, so
SSP_SUPPORT was disabled leading some package to not use SSP.
No information why Glibc and uClibc use libssp, but they may also provide
their own SSP support. uClibc used it own with commit 933b588e25 but it was
reverted in f3cacb9e84 without details.
Create an new configure GCC_LIBSSP and automatically enable SSP_SUPPORT
if either USE_MUSL or GCC_LIBSSP.

Busybox need a special care, link is done with ld, not gcc, leading to
