Added rules to build 64-bit libraries for 64-bit emulator

All ten libraries can now be built in 64-bit named "lib64*" (*)
in addition to the original 32-bit form named "lib*".

Also, dlopen "lib64*so" in 64-bit.

(*) eg. In Ubuntu, all can be built with the following command:
  make out/host/linux-x86/lib/lib64OpenglRender.so \
       out/host/linux-x86/lib/lib64EGL_translator.so \
       out/host/linux-x86/lib/lib64GLES_CM_translator.so \
       out/host/linux-x86/lib/lib64GLES_V2_translator.so

Rules to build static libraries lib64log.a, lib64cutils.a and lib64utils.a
they depend were added in other CLs.
