d5f5045b43 ash: expand: Fix buffer overflow in expandmeta 
Upstream commit:

    Date: Sun, 25 Mar 2018 16:38:00 +0800
    expand: Fix buffer overflow in expandmeta

    The native version of expandmeta allocates a buffer that may be
    overrun for two reasons.  First of all the size is 1 byte too small
    but this is normally hidden because the minimum size is rounded
    up to 2048 bytes.  Secondly, if the directory level is deep enough,
    any buffer can be overrun.

    This patch fixes both problems by calling realloc when necessary.

43dd006222 build system: fix parallel building issue 
The files generated by the include/config/MARKER target are in the
dependency list for applets/applet_tables.
If applets/applet_tables is created first during applets_dir then it will
be created again later as part of $(busybox-dirs).
As a result include/applet_tables.h is created again. This time while other
build commands may need it.

Let applets_dir depend on include/config/MARKER to avoid this particular
race condition and create the header files atomically to ensure that the
compiler never sees incomplete files.
