[Buildroot] [PATCH 1/2] zstd: fix host headers installation

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

Baruch, All,

On 2018-05-08 21:26 +0300, Baruch Siach spake thusly:
> If host-zstd builds when $(HOST_DIR)/include has not been created yet,
> the install-includes target does not create this directory. Instead, the
> install command copies the headers over $(HOST_DIR)/include, thus
> creating a regular file instead of a directory. This leads to the
> following installation failure:
> 
> Installing includes
> install: cannot create directory ?.../host/usr/include/?: File exists
> Makefile:166: recipe for target 'install-pc' failed
> make[1]: *** [install-pc] Error 1
> 
> Add a patch to fix that.

I'm OK that we fix zstd and send them the patch.

Reviewed-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

However, for the target/staging skeleton, we explcitly create the
include directory:
    https://git.buildroot.org/buildroot/tree/package/skeleton-init-common/skeleton-init-common.mk#n34

Why don't we do the same for the host skeleton too?

Regards,
Yann E. MORIN.
