After running the above steps I did the following:

7/ disable compiler cache option in Buildroot
8/ make linux-dirclean linux
9/ diff:

diff output/build/linux-custom/arch/arm/boot/zImage output/build/linux-
custom.orig/arch/arm/boot/zImage
Binary files hbm10/output/build/linux-custom/arch/arm/boot/zImage and
hbm10/output/build/linux-custom.orig/arch/arm/boot/zImage differ

10/ re-enable compiler cache in Buildroot
11/ Binary files hbm10/output/build/linux-custom/arch/arm/boot/zImage
and hbm10/output/build/linux-custom.orig/arch/arm/boot/zImage differ
12/ diff:

diff output/build/linux-custom/arch/arm/boot/zImage output/build/linux-
custom.orig/arch/arm/boot/zImage
(No message)

No idea!
