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.
