package/crosstool-ng: remove

No one is using this host-package, since we no longer have the
crosstool-NG toolchain backend.

-Makefile: allow recursion
-
-When crosstool-NG is used standalone, we completely avoid recursion,
-because the Makefile calls itself only once.
-
-But when used as the buildroot toolchain backend, there is already
-one level of make recursion when we first call the crosstool-NG
-Makefile. And when buildroot is used out-of-tree, we are already
-at the second level of recursion when calling the crosstool-NG
-Makefile.
-
-So, to cope with the situation, just get rid of the recursion test.
-
-This probably won't go upstream.
