Portability fixes and cleanups

Browse Source 
Move Mac OS X IOKit/DirectHW availability checks in the Makefile from
compiler check to pciutils check.

Print the compiler error messages for feature detection.

Add DOS libpci in the Makefile includes only if a PCI-based programmer
was requested.

Restrict mmap usage in ich_descriptors_tool to Unix style systems.

Build ich_descriptors_tool with the correct .exe extension on
DOS/Windows.

Build ich_descriptors_tool by default on x86. (Patch by Stefan Tauner)

Print the Windows version instead of "unknown machine" on Windows.

Don't #define our own __DARWIN__, use the standard OS X detection
method.

Update the README.

Add more generated files to svn:ignore

Corresponding to flashrom svn r1567.
