    kernel.bbclass: set HOSTLDFLAGS in KCONFIG_CONFIG_COMMAND
    
    Kernel v4.14 and newer contain the following in their Makefile:
    
    HOST_LFS_LDFLAGS := $(shell getconf LFS_LDFLAGS)
    HOSTLDFLAGS  := $(HOST_LFS_LDFLAGS)
    
    This breaks our menuconfig, because it can no longer find ncurses if its
    not on the host machine. This can be seen in linux-yocto-dev, for
    example:
    
    [clsulliv at clsulliv build]$ bitbake virtual/kernel -c menuconfig
    
      GEN     ./Makefile
      HOSTLD  scripts/kconfig/mconf
    /home/clsulliv/yocto/poky/build/tmp/hosttools/ld: cannot find -lncurses
    /home/clsulliv/yocto/poky/build/tmp/hosttools/ld: cannot find -ltinfo
    collect2: error: ld returned 1 exit status
    make[3]: *** [scripts/Makefile.host:99: scripts/kconfig/mconf] Error 1
    make[2]: *** [/home/clsulliv/yocto/poky/build/tmp/work-shared/intel-corei7-64/kernel-source/Makefile:504: menuconfig] Error 2
    make[1]: *** [Makefile:146: sub-make] Error 2
    make: *** [Makefile:24: __sub-make] Error 2
    Command failed.
    Press any key to continue...
    
    Fix this by setting HOSTLDFLAGS to ${BUILD_LDFLAGS} in our
    'make menuconfig' command.
