devel/thrift-cpp: fix build with GCC-based architectures

Add -L${OPENSSLLIB} -I${OPENSSLINC} only when base OpenSSL isn't used. Explicitly adding -L/usr/lib make ports GCC link to libstdc++ from /usr/lib instead of /usr/local/lib/gcc8.
Also, explicitly don't use Lua and Qt5, the port uses it if it's installed.
