Here you definetely need to add that this patch depends on this
patchset:
https://patchwork.ozlabs.org/project/buildroot/list/?series=393667
to work-around a gcc bug on htop package.
After the 3 dashes above you should add changes between patch versions like:
V1->V2:
* changed this
* changed that
V2->V3:
* change thee
etc..
and I usually close with other 3 dashes

...to here, since it's part of Buildroot manual and also
you should point "linux-menuconfig and uboot-menuconfig",
but it doesn't make sense to me, so yes please drop it,

Here I would expand comment by pointing that glibc is not suitable and
why. It should be a gcc ICE, so maybe someone can fix or work it around
later with this indication.
