+Hard code library loading
+
+Shortcut the search for the libraries in case the built in
+find_library is broken.
+
+As buildroot does not ship any of the external programs that the core
+procedure use to find libraries use the canonical name of the shared
+object and load it.
+
+In this case this affects loading libftdi and libusb.
+
+This should be reliable as we specify said libs as dependencies of
+this package.
