When doing a cross compiling it is common to use EXTRA_CFLAGS with
--sysroot option to point to alternate root filesystem. This already
works as expected for objects and executables, it just doesn't work
correctly for shared libraries.

When a shared library is linked using CC this flag needs to
be passed in order for libraries to be found.
