cmake: s/-Wl,-export-dynamic/$CMAKE_EXE_EXPORTS_C_FLAG/

* s/-Wl,-export-dynamic/$CMAKE_EXE_EXPORTS_C_FLAG/
  this address the issue on osx:

    ld: unknown option: --export-dynamic

  because ld on osx does not support `-export-dynamic`, it supports
  `-export_dynamic` though.

  CMAKE_EXE_EXPORTS_C_FLAG is set to -Wl,-export-dynamic on FreeBSD
  and GNU/Linux.
