qt: fix static linking `-ldl` option is used unconditionally in `QMAKE_LIBS_DYNLOAD` while libdl is not supported when libc is static. As the value of `QMAKE_LIBS_DYNLOAD` goes into 'Libs.private' field of the pkgconfig files created by qmake, static linking with qt will fail with: /usr/bin/ld: cannot find -ldl Fix this issue by adding a build test to configure to check if libdl is supported. `QMAKE_LIBS_DYNLOAD` in "src/corelib/plugin/plugin.pri" is now used only if libdl is available.
