plan9: alternative build for libbio changes
       utilizes core Plan 9 libbio implementation
       by adding the missing macros and functions
       to a go-specific libbio target.

Sorry, but no more plan 9 changes until after Go 1.2 is out.

I'd like to move src/lib9/bio_plan9.c to src/libbio and extract the functions
from bgetc.c and bputc.c.  This would allow just the four functions to be
compiled and installed into $GOROOT/pkg/obj/plan9_$objtype/fname.$O.  This keeps
the bio.h header clean for Plan 9 and other systems without adding additional
#ifdefs to tons of other code, and for those still needing to link libbio.a,
it's all there as needed.

I think this was tagged after an recent sync.  I've moved the lib9/bio_ addition
back into libbio and cleaned up the dist/build.c.
