At present packaging the required DLLs of QEMU executables is a manual process, and error prone. Actually build/config-host.mak contains a GLIB_BINDIR variable which is the directory where glib and other DLLs reside. This works for both Windows native build and cross-build on Linux. We can use it as the search directory for DLLs and automate the whole DLL packaging process.
