win32: fix compilation on MinGW

The commit 74df1d8e05 (and f752212c62) replaced the configure
endian check with byte order macros defined by standard headers. It
turns out that MinGW-w64 actually doesn't define these macros in the
sys/types.h system header. (I assumed it does, because a quick test
seemed to work. But that was because gcc -W -Wall doesn't warn against
undefined macros. You need -Wundef for that.) MinGW-w64 has a
sys/params.h header defining these macros, but sys/types.h doesn't
include it, so it's useless without special casing the mplayer code.
Add a hack top configure instead. Define the macros directly, and
assume MinGW-w64 only works on little endian machines.

The other changes are basically random typos and superficial oversights.
