[FFmpeg-devel] [PATCH] configure: use subarch instead of arch to create .def files on mingw

[James Almer]

arch is "x86" regardless of target being x86_32 or x86_64, and if
configuring with asm disabled it's "c" instead.
Using subarch (Always either "x86_32" or "x86_64") and adapting
makedef makes sure the symbols are always detected correctly on
x86_32.
