Only used for SITE=USN now, but feel free to test and use it for other SITE.

+#   Check that the ipx file used in the currently defined Quartus seems correct
+#
+# Description:
+#   Will check if all the pathes present in:
+#   $UNB/Firmware/synth/quartus/user_components.ipx
+#   are also present in:
+#   ~/.altera.quartus/ip/<current quartus>/ip_search_path/user_components.ipx
+#   Other pathes can also be present there and will not raise errors but a
+#   warning is issued
