The BeOS port uses private syscalls exported by libroot.so to implement the intel access methods.
The Haiku port uses ioctls to the /dev/misc/poke device driver (use originally for debugging with
/bin/poke) to implement the intel access methods. BeOS has non-standard arch names, so we map them
to i386 and powerpc in the configure. Updated README and pcilib.man accordingly.

GNU Hurd (direct port access)
Windows (direct port access)
CYGWIN (direct port access)
+ BeOS (via syscalls)
+ Haiku (via /dev/misc/poke)
It should be very easy to add support for other systems as well (volunteers
wanted; if you want to try that, I'll be very glad to see the patches and
