| 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. |
