[U-Boot] [PATCH V2] pylibfdt: Add missing CC and LD to Makefile

[Marek Vasut]

Add missing CC and LDSHARED variables to the Makefile to pass the
correct C compiler and linker path to the build of _libfdt.so .

Note: This fixes the long standing issue when building U-Boot with
      OE for qemux86 or qemux86_64, where the build will try to use
      the host compiler, which OE will block and thus the build will
      crash on missing compiler/linker binary. With this patch, the
      OE will correctly pass in the compiler/linker generated during
      the build, just like it does for all the other tools.
V2: Drop unset CC
