Patch: Include WARN_CFLAGS in CFLAGS passed for building fixinc.sh

This patch hasn't been reviewed yet.  Although passing WARN_CFLAGS to
mkfixinc.sh isn't very important at this time, I think there should be
consistency in the passing the flags to the various sub-makes.

I revamped the CFLAGS handling so that different flags could be used for
the initial compilations which might be done with a native compiler.  The
Makefile variables WARN1_CFLAGS and WARN2_CFLAGS are set by configure.
Currently, they are used for warning options and a compiler dependent
option on the vax.  Potentially, this method could be used to supply
compiler options on many other platforms.

I also noticed yesterday that the method of handling WARN_CFLAGS didn't
get updated for bootstrap4.  Thus, I have updated the original patch.
I have tested the patch with a complete bootstrap through to stage4
under i686 linux.
