Build related improvements, better ASMJIT_NO_STDCXX support

Browse Source 
* Added more cmake options to control features to be built
  * Added a detection whether to link to libpthread (if not part of libc)
  * Added a detection whether to link to librt (if not part of libc)
  * Removed pure virtual functions as this collides with -nostdlib
  * As a result the support for ASMJIT_NO_STDCXX has improved
