[Buildroot] [PATCHv2] package/mtd: needs zstd

[Yann E. MORIN]

From: Julien BOIBESSOT <julien.boibessot@armadeus.com>

For the target variant, zstd is a mandatory dependency when ubifs-tools
are enabled. For the host variant, it is an unconditional dependency.

But in configure, as yhou already quoted, we can see that zstd is
mandatory for ubifs:

    AM_COND_IF([BUILD_UBIFS], [
                need_uuid="yes"
                need_xattr="yes"
                need_zlib="yes"
                need_lzo="yes"
                need_zstd="yes"                   <<<<<<<<
                need_openssl="yes"
        ])

So, zstd is not a conditional dependency when ubifs is enabled. Or do I
still need to get more cofee? ;-)

Regards,
Yann E. MORIN.

well in configure it can also be disabled (like openssl):

    Optional Packages:
      ...
      --without-zstd          Disable support for ZSTD compression

If your patch is OK for Thomas, it is OK for me (to select zstd by
default when ubifs is choosen in mtd) ;-)

Regards,
Julien

Indeed, I've just tested, and it is really optiona. I've sent a v3.
