Disable shared library support when compiler links statically
When a user or a compiler wrapper adds '-static' to the compiler flags then it will always link static binaries. Detect this from the compiler id binary and disable TARGET_SUPPORTS_SHARED_LIBS. This will prevent projects from accidentally adding shared libraries when the toolchain does not support them. It also helps CMake avoid linking with flags that require shared libraries to be supported.
