Subject: [PATCH] [flang][CMake] CYGWIN: Fix undefined references at link time.

While building the source of flang on CYGWIN, the process suddently stopped with lot of "Undefined reference" errors at link time. According to the statement that a shared library can't have undefined references on Windows, I applied the same fix to CYGWIN with this patch.
