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.
