[Buildroot] [PATCH v7 2/8] Makefile: move definition of TARGET_DIR inside .config condition

[Yann E. MORIN <yann.morin.1998@free.fr>]

Thomas, All,

On 2018-12-28 11:43 +0100, Thomas Petazzoni spake thusly:
> In a follow-up commit introducing per-package directory support, we
> will need to define TARGET_DIR in a different way depending on the
> value of a Config.in option. To make this possible, the definition of
> TARGET_DIR should be moved inside the BR2_HAVE_DOT_CONFIG condition.
> 
> We have verified that $(TARGET_DIR) is only used within the
> BR2_HAVE_DOT_CONFIG condition. Outside of this condition, such as in
> the "clean" target, $(BASE_TARGET_DIR) is used.
> 
> Suggested-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>
> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
