+# In the below dict:
+
+# - 'conditions' indicate the cumulative conditions under which the
+#   toolchain will be made available. In several situations, a given
+#   toolchain is usable on several architectures variants (for
+#   example, an ARMv6 toolchain can be used on ARMv7)
+# - 'test_options' indicate one specific configuration where the
+#   toolchain can be used. It is used to create the runtime test
+#   cases. If 'test_options' does not exist, the code assumes it can
+#   be made equal to 'conditions'
+# - 'prefix' is the prefix of the cross-compilation toolchain tools
