v0.11.0-rc0-1630-g51cc2e7 fails to build on mingw with gcc version 3.4.5 (mingw32 special)
and GNU Make version 3.79.1.

gcc -I/home/sh/vm/qemu/v0.11.0-rc0-1630-g51cc2e7/slirp -Wold-style-definition -I.

audio/sdlaudio.c:25:24: warning: SDL_thread.h: No such file or directory

Notice the missing parameter for "-MT" with sdlaudio, but not mixeng. Before commit
02d5467e9f43dac05f04999e387108ca4c8ba140 "-MT" was followed by "-U_FORTIFY_SOURCE", but now it's "-I/mingw/include/SDL"
which gets swallowed.
