configure: Generate config files for PCI_OS_WINDOWS

This change adds support for using configure script for cross-compiling
pciutils on Linux for Windows platforms.

Following command can be used to compile pcitils for Windows platform:

  make CROSS_COMPILE=i586-mingw32msvc- HOST=i386-windows ZLIB=no IDSDIR=.

PCI_OS_WINDOWS does not support BSD DNS functions, so do not automatically
enable DNS support.

Library ioperm is cygwin specific and is used only for PCI_OS_CYGWIN.
