[CMake] Doesn't support SHARED libraries during cross compiling using ARM RVCT40.

[jianhua]

Hi Neundorf;

Thanks for your continuous help, you have helped me to solve 2 threads now.

After remove line SET (CMAKE_SYSTEM_NAME Generic)  now it works.

The target device OS is Brew MP, something like eCos, but it is much simpler,  powered by Qualcomm.
