While most of the target's contents are split into subtargets, the
base-files are maintained for the target as a whole.
However, OpenWrt already implements a mechanism that will use (and
even prefer) files in the subtargets' directories. This can be
exploited to make several scripts subtarget-specific and thus save
some space (especially helpful for the tiny devices).
The only script remaining in parent base-files is
/etc/hotplug.d/ieee80211/00-wifi-migration, everything else is
moved/split.
Note that this will increase overall code lines, but reduce code
per subtarget.
base-files ipk size reduction:
master (generic) 49135 B
split (generic) 48533 B (- 0.6 kiB)
split (tiny) 43337 B (- 5.7 kiB)
split (nand) 44423 B (- 4.6 kiB)
Tested on TL-WR1043ND v4 (generic) and TL-WR841N v12 (tiny).

Add out of the box support for 802.11r and 802.11w to all targets not
suffering from small flash.

Mathias did all the heavy lifting on this, but I'm the one who should
get shouted at for committing.

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
