[Buildroot] [PATCH 1/1] Makefile: add $BINARIES_DIR dependency to target-post-image target

[Yann E. MORIN]

Brent, All,

Thanks for your contribution.

On 2019-07-12 16:10 +0000, Brent Generous spake thusly:
> Without this dependency, there is no guarantee that the $BINARIES_DIR
> has been created before this point. This can cause commands that intend
> to copy a file into $BINARIES_DIR to instead copy to a file named
> $BINARIES_DIR, causing later commands to create this directory to fail.

We've discussed this today during the developpers meeting, andwe
concluded that the real solution would be to create the directory right
before calling the post-image scripts. I've respun a v2:

Can you confirm this also fixes your issue?
