[Buildroot] [PATCH v2 01/15] package/pkg-autotools.mk: Factorize hooks.

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

Johan, All,

On 2014-11-07 14:28 +0100, Johan Oudinet spake thusly:
> Define common macros only once (instead of as many times as
> there are inner-autotools-package calls).
> Factorize LIBTOOL_PATCH_HOOK and AUTORECONF_HOOK to avoid duplicated
> code.

Sorry it takes so long to review this series. Touching the infra is not
for the faint of heart, and reviews are really complex and time-consuming.

Hmm... This patch does nore than extract the definitions out of
inner-autotools-package; it also reworks the way they are called.

I'd rather we get this split in at least two patches:
  - one that does the move proper
  - one that reworks the calls

It will be easier to review.

I think you got the order wrong here: we want the libtool patch to be
applied _before_ we autoreconf.

So, this last if-block should be the very first thing to do right after:
    ifeq ($$($(2)_AUTORECONF),YES)

I'll do some more in-depth review later, presumably after you split the
patch. If you don;t have time for that, I can see to get it done
tomorrow.

Again, sorry for the delay, reviewing infra changes is really tricky...

Yann E. MORIN.
