+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.
+
+Upstream-Status: Inappropriate [OE Specific]
