[Buildroot] [PATCH 2/2] core: remove redundant "override O := $(O)"

The top-level Makefile contains an "override O := $(O)" statement that
is purportedly required to make sure the O flag doesn't leak into the
environment of sub-makes. However, since commit 173135d, there is
already an "override O := ..." a few lines down. Therefore, the first
override is redundant.

I haven't been able to reproduce the issue mentioned in the comment
(tested by printing the value of $(O) in a dummy package) with make 4.1.
I therefore removed the comment completely.
