Make some adjustments to the build system to allow busybox-w32
to be built with w64devkit:
- Strip drive prefix from CURDIR in Makefile to avoid confusing
make with colons.
- Limit file redirection to a subshell in the usage_compressed and
embedded_scripts scripts. Otherwise it isn't possible to move
the open generated file on Windows.
- Change the option tests in Kbuild.include to allow for /dev/null
not existing on Windows.
- Create host binaries without a '.exe' extension. Otherwise they're
rebuilt more often than necessary.
- Modify split-include.c to allow for Windows' popen() not expanding
wildcards.

Commit 4bdc914ff (build system: fix compiler warnings) added a
test on the return value of fgets() in split-include.c.
During bisection it's possible to go back to a state where a
configuration value didn't exist. This results in an empty
include file corresponding to the missing feature. If a
subsequent bisection returns to a state where the feature exists
split-include treats the empty file as an error and the build
fails.
Add a call to ferror() to distinguish between fgets() failing
due to an error and due to there being no data to read.

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).
