+- Also, I want to clarify one point. If you build a toolchain with crosstool-NG
+  and you happen to sell, deliver, or otherwise publish this toolchain to a
+  third party, I consider crosstool-NG as being part of the sources needed to
+  rebuild the afore-mentioned toolchain, alongside with all other source code
+  that third party is otherwise entitled to receive, due to other licenses of
+  the different components. See licenses.d/gpl.txt, section 3, which reads:
+   > For an executable work, complete source code means [...], plus the
+   > scripts used to control compilation and installation of the executable.
+
+  In short: crosstool-NG is the part refered to as "the scripts to control
+  compilation and installation of the exectuable", it being the toolchain in
+  our case; and as such you must make it available, in conformance to the
+  GPLv2, see above.
