[Buildroot] [PATCH 2/3] package/automake: also include autoconf-archive in search paths

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

All,

On 2020-02-09 16:12 +0100, Yann E. MORIN spake thusly:
> Since d255b67972 (autotools: do not overwrite first include path), the
> ordering of include paths has changed: the system directories are
> specified with explicit options passed to autoreconf, which means that
> any directory specified in the package _AUTORECONF_OPTS are no longer
> first:
> 
>   - in package/autoconf/autoconf.mk, we define AUTORECONF as:
>     AUTOCONF = $(HOST_DIR)/bin/autoconf -I "$(ACLOCAL_DIR)" -I "$(ACLOCAL_HOST_DIR)"
> 
>   - in package/pkg-autotools.mk, we call AUTORECONF with:
>     $($(PKG)_AUTORECONF_ENV) $(AUTORECONF) $($(PKG)_AUTORECONF_OPTS)
> 
> For a package that needs autoconf-archive, this means that it has to
> provide a custom include directive, in its own _AUTORECONF_OPTS. This in
> turn means that this directory becomes the first, and goes directly
> opposite to what d255b67972 was supposed to accomplish.
> 
> However, the path to the autoconf archive macro directory is mnot
> searched by default either, so a package has no way to add such an
> aclocal include directive.
> 
> We can only add it in the global search directory, and we do so only for
> those packages that have autoconf-archive in their dependencies.

This makes check-package whine because it is not indented. Sigh...
Indenting with a TAB fixes the check-package error, and is still a
working fix.
