Subject: byacc: do not reorder $CC and $CFLAGS

byacc tries to process $CC and decide which part should belong to CC and which
part should below to CFLAGS and then do reordering. It doesn't make much sense
for OE. And it doesn't do its work correctly. Some options are dropped.

Delete all these stuff so that we could have all options we need.
