pciutils to be compiled with DJGPP. I originally developed this patch in 2010,
and I respun it for latest pciutils.

* Add DJGPP as an OS target
* Stop if endianess macros are not defined
* Introduce new intel_io_lock/unclock function to synchronize
  I/O operations.

There is a small issue left that "lspci" and "lspci.exe" are created. The ".exe" variants
