Thanks for clarifying - _but_ if I rerun "make kernel_menuconfig"
with current trunk I get several big changesets that might break
some targets if I look at the symbol changes on some of them:

Example:
x86 with selected KPROBES in menuconfig needs 
# CONFIG_X86_DECODER_SELFTEST is not set

but
X86_DECODER_SELFTEST is removed from target/x86/config-3.18 with "make kernel_menuconfig"
but other symbols from arch/x86/Kconfig.debug are kept in that file

make target/linux/compile : does not work because the missing symbol
make kernel_oldconfig : does not add or question this symbol 

a patch that has "make kernel_menuconfig" changes
for all targets (might be missing some subtargets) is available at:
https://github.com/plntyk/openwrt-patches/blob/master/kernel_refresh/0016-refreshes-according-to-make-kernel_menuconfig.patch
(from a tree where some changes regarding kernel version/symbols were already applied)

I did run "make dirclean" before arch switching and a target/linux/clean run before running make kernel_menuconfig.

I really dont get it where the menuconfig changes are coming from
Would patching the arch/<targetarch>/configs/*defconfig help/be the correct fix?
The patch that does this sort of thing for brcm2708 looks really bad 
(patch #023)
"Malta"(-LE) maybe needs a defconfig since kernel_menuconfig wants to switch to the big endian variant

Those "instable" symbols are a bit annoying when they will get "accidentally" reverted
