[Buildroot] [PATCH v3 2/6] zstd: add host libzstd support

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

Peter, All,

On 2018-04-16 21:39 +0200, Peter Seiderer spake thusly:
> For the host only the libzstd library is built (no
> need for host-lz4 host-xz host-zlib dependencies
> because they affect only the cmdline tool).
> 
> Signed-off-by: Peter Seiderer <ps.report@gmx.net>

Just a note, see below...

For the build command, you do:      -C $(@D) lib
while for the install, you do:      -C $(@D)/lib install

It is not very consistent (not your fault, just the package's). But
would it be possible to build with: -C $(@D)/lib

This way, we would get a semblance of artificial consistency...

But that does not bar this from be applied as is...

Yann E. MORIN.
