I think I've explained this in the non-quoted here part.

What problem are you trying to attack, I fail to see?
-DNO_CPU_CFLAGS is already there, if that's what you mean:
BMAKE=3D MAKEOBJDIRPREFIX=3D${WORLDTMP} \
${BMAKEENV} ${MAKE} -f Makefile.inc1 \
DESTDIR=3D \
BOOTSTRAPPING=3D${OSRELDATE} \
-DNO_HTML -DNO_INFO -DNO_LINT -DNO_MAN -DNO_NLS -DNO_PIC \
-DNO_PROFILE -DNO_SHARED -DNO_CPU_CFLAGS -DNO_WARNS
^^^^^^^^^^^^^^^
XMAKE=3D TOOLS_PREFIX=3D${WORLDTMP} ${BMAKE} -DNO_FORTRAN -DNO_GDB
^^^^^^^^
=2E.. and has the following effect:
$ make -V CFLAGS CPUTYPE=3Dopteron=20
-O2 -fno-strict-aliasing -pipe -march=3Dopteron
$ make -V CFLAGS CPUTYPE=3Dopteron -DNO_CPU_CFLAGS
-O2 -fno-strict-aliasing -pipe
But it doesn't really matter since building host's libraries that
ARE used to build toolchain might have been built using optimized
CFLAGS. See other posts where people go into more details what
should be the conditions to allow NFS-mounted src/ installs.
