+Using as a backend for a build-system |
+--------------------------------------+
+
+Crosstool-NG can be used as a backend for an automated build-system. In this
+case, some components that are expected to run on the target (eg. the native
+gdb, ltrace, DUMA...) are not available in the menuconfig, and they are not
+build either, as it is considered the responsibility of the build-system to
+build its own versions of those tools.

+your build-system, you have to set and export this environment variable:
+ CT_IS_A_BACKEND=y
