    build: fix stale package install stamps for unselected variants
    
    When a package variant changes from =y to =m, its .install stamp file
    was not being cleaned up, causing both variants to appear in the
    package install list.
    
    Fix by making compile depend on prepare-package-install, ensuring
    the stamp file is always cleared. Only =y packages recreate it.
