toolchain-wrapper: remove remaining references to HOST_DIR/usr
Commit
14151d77af20ec50eeba6e30465debf87b35faaa that eliminated
$(HOST_DIR)/usr seriously missed the toolchain-wrapper - only a single
reference was updated, the other three were missed. Commit
015d68c84c9c6ad6f6d41f181d19d813f309088b removed one more. This commit
finally removes the two remaining ones.
