rNnot quite: In pkg.install "make install" installs to
platform-<xyz>/packages/<pkg>/ and int pkg.install.post everything there is
copied to sysroot-target/ (with some path fixups).

No need for that. platform-<xyz>/packages/<pkg>/ contains all the files
installed by "make install", so just use install_tree in targetinstall:

	@$(call install_tree, <pkg>, 0, 0, -, /)
