Yann E. MORIN d9ff62c4cd pacakge: drop remnants of $(HOST_DIR)/usr 
It's been ages (5 years at the next release) that we've not installed
host packages in $(HOST_DIR)/usr, but we still have a few packages that
reference it or install things in there.

Drop all of those in one fell swoop.

The run-time test still succeeds, and the following defconfig, which
should exercise all touched packages [*], does build:

    BR2_x86_i686=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_INIT_NONE=y
    BR2_SYSTEM_BIN_SH_NONE=y
    # BR2_PACKAGE_BUSYBOX is not set
    BR2_PACKAGE_GAWK=y
    BR2_PACKAGE_GETTEXT=y
    BR2_PACKAGE_ABOOTIMG=y
    BR2_PACKAGE_DBUS_PYTHON=y
    BR2_PACKAGE_OLA=y
    BR2_PACKAGE_JIMTCL=y
    BR2_PACKAGE_LUA=y
    # BR2_PACKAGE_LUA_32BITS is not set
    BR2_PACKAGE_ARGPARSE=y
    BR2_PACKAGE_PERL=y
    BR2_PACKAGE_PHP=y
    BR2_PACKAGE_PHP_APCU=y
    BR2_PACKAGE_PHP_LUA=y
    BR2_PACKAGE_PHP_PAM=y
    BR2_PACKAGE_PHP_PECL_DBUS=y
    BR2_PACKAGE_PYTHON3=y
    BR2_PACKAGE_PYTHON_CRYPTOGRAPHY=y
    BR2_PACKAGE_PYTHON_PLY=y
    BR2_PACKAGE_PYTHON_PYBIND=y
    BR2_PACKAGE_LIBVA=y
    BR2_PACKAGE_BIND=y
    BR2_PACKAGE_BIND_SERVER=y
    BR2_PACKAGE_BIND_TOOLS=y
    BR2_PACKAGE_APPARMOR=y
    BR2_PACKAGE_APPARMOR_BINUTILS=y
    BR2_PACKAGE_APPARMOR_UTILS=y
    BR2_PACKAGE_APPARMOR_UTILS_EXTRA=y
    BR2_PACKAGE_APPARMOR_PROFILES=y
    BR2_PACKAGE_REFPOLICY=y
    BR2_PACKAGE_URANDOM_SCRIPTS=y
    BR2_PACKAGE_BASH=y
    # embiggen-disk to exercise go
    BR2_PACKAGE_EMBIGGEN_DISK=y
    BR2_TARGET_GRUB2=y
    BR2_TARGET_GRUB2_I386_PC=y
    BR2_TARGET_GRUB2_I386_EFI=y

[*] exceptions:
  - zfs was not tested: it needs a kernel to be built;
  - compiler-rt was not tsted: it needs llvm to be built, that takes
    ages, and other packages already reference the correct location for
    llvm-config, so it was assumed that is OK.
