kbuild: support at least non-interactive mode on Windows

without POSIX, kbuild has some trouble compiling its support
executables. Luckily, the parts that really lean on POSIX functionality
are pretty much all only needed when configuring the build
interactively.

When compiling BusyBox for Win32, we do not actually need interactive
configuration at all: we simply choose the default. Therefore, a lot of
the stuff that is typically built for the Kconfig system is totally
unnecessary (such as: compiling documentation via fork()&exec(), changing
the window size, etc).

Liberally put all of the problematic code behind #ifndef __MINGW32__
guards, just to get `make mingw64_defconfig` going in Git for Windows'
SDK (which is a special-purpose version of MSYS2).
