[Buildroot] [PATCH 1/2] package/pkg-generic.mk: create folders before calling hooks

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

Thomas, All,

On 2020-03-12 10:15 +0100, Thomas Petazzoni spake thusly:
> In commit 0e2be4db8ab01d479177a3a187c22525752195ae
> ("package/pkg-generic: make file list logic parallel build
> compatible"), the logic to create the list of files installed by a
> particular package was significantly reworked to be compatible with
> top-level parallel build.
> 
> Before this commit, there was only a after-install step of listing the
> files in HOST_DIR/TARGET_DIR/STAGING_DIR. But after this commit, we
> now have a before-install logic and an after-install logic.
> 
> It turns out that when the before-install logic is called for the very
> first host package, $(HOST_DIR) doesn't exist yet, and therefore the
> cd $(2) fails, with an error message:
> 
> /bin/sh: line 0: cd: /home/thomas/buildroot/output/host: No such file or directory
> 
> In fact, $(HOST_DIR), $(STAGING_DIR), $(TARGET_DIR) and
> $(BINARIES_DIR) are created by the make rules for host installation,
> staging installation, target installation and images installation, but
> *after* calling the step_start hooks.
> 
> So, we simply fix this problem by creating the directories *before*
> calling the step_start hooks.

Applied to master, thanks.

I just changed the commit title: s/folders/directories/
