The currently installed patch is wrong and should be backed out.  For
native builds, it is necessary to have different CFLAGS for stage1 and
subsequent stages on some hosts.  The stage1 compile flags are the
default values set in the Makefile.  These currently are set by configure
and not directly passed to the stage1 build.  Passing STAGE1_CFLAGS
from the toplevel Makefile would apprear to provide a method to override
the defaults set by configure.
