Bug#55647:CMake build rebuilds some libraries twice for embedded
Bug#55647:CMake build rebuilds some libraries twice for embedded

A  simple version of the patch : add WITH_PIC to debug compilation.

Engines that are not dependent on internal stuff (like THD structure) 
will not be recompiled for embedded in debug mode.

Examples of such engines are : archive, federated, innodb. Engines
with dependencies on internals (myisam,heap,myisammrg) will still be 
fully recompiled.
