Here is the template for all cross pkg-configs:
http://repo.or.cz/w/qemu/ar7.git/blob_plain/HEAD:/scripts/cross-pkg-config

See also http://patchwork.ozlabs.org/patch/114242/

Maybe I should resend that patch.

I think -mthreads is essential (needed for thread local storage),
and -D_POSIX=1 is also needed for 64 bit builds.

Maybe you can try my QEMU fork from http://repo.or.cz/w/qemu/ar7.git
and see whether it works for you. My binaries are based on that code.
If it works, we have to look which patches are missing in the official
QEMU version.

SDL comes from a locally cross built libSDL. I never had time to put
it into a Debian package. Maybe it is better for your tests to build
without SDL support, because the SDL init code redirects stdin and
stdout to files which complicates things even when you run QEMU
with SDL disabled.

It has a built-in magic: all DLL files from $(SRC_PATH)/dll/w64 are
taken for the 64 bit build (w32 for 32 bit build).

Get a list of all needed DLL files either by try and error or by using
tools and copy them (or make symbolic links) to that directory.
Here are the files for 32 bit for my configuration:

dll/w32/freetype6.dll
dll/w32/pdcurses.dll
dll/w32/libgio-2.0-0.dll
dll/w32/libfontconfig-1.dll
dll/w32/libpangoft2-1.0-0.dll
dll/w32/libpangocairo-1.0-0.dll
dll/w32/libgtk-win32-2.0-0.dll
dll/w32/libatk-1.0-0.dll
dll/w32/libpangowin32-1.0-0.dll
dll/w32/intl.dll
dll/w32/libpango-1.0-0.dll
dll/w32/libgcc_s_sjlj-1.dll
dll/w32/libgdk_pixbuf-2.0-0.dll
dll/w32/libglib-2.0-0.dll
dll/w32/libssp-0.dll
dll/w32/zlib1.dll
dll/w32/libgmodule-2.0-0.dll
dll/w32/libcairo-2.dll
dll/w32/SDL.dll
dll/w32/libgthread-2.0-0.dll
dll/w32/libexpat-1.dll
dll/w32/libpng14-14.dll
dll/w32/libgobject-2.0-0.dll
dll/w32/libgdk-win32-2.0-0.dll
dll/w32/libstdc++-6.dll

There is an nsis macro W64 which switches the program directory (see 
qemu.nsi).
Are you using the packages from Debian (here those for Wheezy):

ii  nsis 2.46-7                        amd64        Nullsoft Scriptable 
Install System (modified for Debian)
ii  nsis-common 2.46-7                        all          Nullsoft 
Scriptable Install System stubs and plugins
