 I'm baffled.  I've just completed this from one of my x86 LFS-6.3
systems.  Mine was fine, as I expected.  What baffles me is that
I've got a lot more going on.

 Mine has a _lot_ more after it leaves libdecnumber, and among other
things that includes creating crtbegin.o and such like.

 At this point mine has
[...]MULTILIB_CFLAGS="" T= crtbegin.o crtend.o crtbeginS.o
crtendS.o crtbeginT.o ecrti.o ecrtn.o ncrti.o ncrtn.o crtsavres.o

make[4]: `crtend.o' is up to date.

make[4]: `crtendS.o' is up to date.
make[4]: `crtbeginT.o' is up to date.
cat ../../gcc-4.2.4/gcc/config/rs6000/eabi-ci.asm >ecrti.S

 it then runs through ecrtn.S ncrti.S ncrtn.S crtsaveres.S and then
creates mcrtn.o and crtsaveres.o.

 Like I say, I've really no idea why yours is so different.  But
then, I try not to get too involved in the mechanics of the
toolchain.  It seems to think that a lot of the basic object files
(those which get linked into the executables gcc builds) don't need
to be made or re-made, which implies it might be confused about what
architecture it is building for, or where it should be building.

First question: for each of the two gcc builds, did you apply all of
the patches listed for that build, and only those patches, and did
you successfully add the STARTFILE_PREFIX_SPEC to the end of what
was in gcc/config/rs6000/linux.h ?

Second question: what do you have for CLFS_HOST and CLFS_TARGET ?  I
hope you're going to tell me i686-pc-linux-gnu and
powerpc-unknown-linux-gnu.

Third question: did you pass all the correct options to the binutils
configure ?
