Host dependency issues

[quic_pkommu]

Hi  Developers,
Hope all is well 😊 

We are trying to enable selinux ,   21.02   where the default mtd-utils  (for NAND /ubifs ) are not supporting selinux . 
So  we moved to  mtd-utils 2.1.5 , where its fixed but we are seeing this build time  failure. 

Problem :
During mkfs.ubifs  host utility compilation   make system /autoconfig  is checking for the    following  depenecy as these are the first to get compile   (libselinux is much later )
LIBSELINUX , 
SELinux/selinux.h
Selinux/label.h

So when compiling mtd-utils  this artifacts are  not found in the expected path  and  autoconfig  is assuming no-selinux and  disable SELinux . 
Where most of the include / Lib are in hostpkg which is not even created at that point of  time .
If I compile just mtd-utils post libselinux ( clean mtd-utils )  it works .
  .

What we had tried :  

HOST_BUILD_DEPENDS:=libselinux/host
DEPENDS:=libselinux

## under define Package/mtd-utils/Default
DEPENDS:=@NAND_SUPPORT  +libselinux
But all this options seem to be used in enabling and disabling options at menuconfig level ,  

Is there a way that we can create a inter dependent , or make  selinux compile first and later the mtd-utils ?
