Fix hwaccess (again).

I completely forgot about NetBSD in r1638 which was broken since then.
Also, on OpenBSD use iopl again and refine the warning in case we have
insufficient privileges.
Thanks to Jonathan A. Kollasch for his help in getting the details right.

Add support for AMD Geode's MSR on OpenBSD.

Previously the default implementation was used, which always failed.
On other systems than the Geode the code is not equal to that anymore,
but should not explode because setup_cpu_msr() returns an error and
therefore no other MSR functions should be called.

Various cross-platform fixes.

Improve compilation with libpayload (compiling flashrom.c and
linking is still broken):
 - disable Ponyprog (which enforced serial.c compilation)
 - make errno available where it is needed

Fix internal.c for non-x86 and enable cb parsing on ARM.

Fix mingw builds by using its __USE_MINGW_ANSI_STDIO macro
and gnu_printf definition for printf format style checking.
See http://sourceforge.net/apps/trac/mingw-w64/wiki/gnu%20printf
This requires inclusion of stdio.h in flash.h.

Fix order of libraries in the Makefile:
FEATURE_LIBS needs to come *after* PCILIBS in case ZLIB is needed by it.
