uboot: (firmwareOdroidC2/C4) don't invoke patch tool, use patches = [] instead

https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+Subject: [PATCH] Support shared library build
+
+Patch taken from [the ACL2 Books documentation][1].
+
+- Add " -fPIC" to the CXXFLAGS to build position-independent code,
+  required for shared libraries.
+
+- Add the line "export CXXFLAGS" below the setting of CXXFLAGS, so that
+  those flags apply to the recursive make of the core solver library.
+
+- Fix a typo: replace the occurrence of "CXXLAGS" with "CXXFLAGS".
