[Buildroot] [PATCH] post-build: reimplement using a for loop and make verbose

[Luca Ceresoli]

Make the post-build system similar to the rootfs overlay system. This allows to
show each script filename before execution.

I don't have a strong opinion on whether this is useful or not, but if
it gets applied, I'd like the same to be done for post-image scripts,
in order to keep the consistency.

Thanks!

Alternatively, you could just move the MESSAGE into the loop instead
of relying on shell loops.  That would keep things more in make, if
that's desired.

	@$(foreach s, $(call qstrip,$(BR2_ROOTFS_POST_BUILD_SCRIPT)), \
		$(call MESSAGE,"Executing $(s)"); \
		$(s) $(TARGET_DIR)$(sep))

To me it is useful each time multiple post-build scripts are used, 
because is
makes it easy to understand what's happening and which scripts you are 
running
(and which you are not running).
E.g., I have multiple products with a common base, plus some "optional" 
features.
Some features needs a specific post-build script. Each product 
implements a subset
of the features, but these subsets overlap between different products.
When a build a product's rootfs it is useful to see if I am running all 
and only
the correct post-build scripts: the "common base" script, plus the 
scripts for the
wanted features.

Of course I agree this change should be done also in the post-image scripts.
I will submit a patchset that does also this.

It is actually cleanerand should also be more efficient(FWIW).

Sending a v2 patchset with this implementation.
