Subject: [PATCH 4.18 132/145] kconfig: fix "Cant open ..." in parallel build

4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Masahiro Yamada <yamada.masahiro@...ionext.com>

commit 98a4afbfafd226636cd6bb6a1208b3693daff2b1 upstream.

If you run "make menuconfig" or "make nconfig" with -j<N> option in a
fresh source tree, you will see several "Can't open ..." messages:

  $ make -j8 menuconfig

    HOSTCC  scripts/kconfig/mconf.o
    HOSTCC  scripts/kconfig/zconf.tab.o
    HOSTLD  scripts/kconfig/mconf

Correct dependencies to fix this problem.
