[LLVMdev] Problem with llvm-gcc 'make' and arm-none-linux-gnueabi-as

I recently attempted to update the ARM cross-compilation setup I had with
llvm, and it did not work, so I wanted to revert back to my initial
configuration.  I reconfigured/make/make install'ed my llvm which executed
fine, and then cleared out my llvm-gcc obj and install folders, and
reconfigured gcc from within llvm-gcc/obj as follows:

../llvm-gcc-4.2-2.9.source/configure --target=arm-none-linux-gnueabi
--disable-optimized --disable-multilib --disable-bootstrap --disable-shared
--enable-checking --enable-languages=c,c++

This seemed to work fine.   However, when I then executed 'make', it would
make it about 10 minutes into the build and then terminate as follows:

./llvm-gcc-4.2-2.9.source/gcc/../libdecnumber -I../libdecnumber
unrecognized option '-Qy'
make[2]: *** [g++spec.o] Error 1
make[2]: Leaving directory
make[1]: *** [all-gcc] Error 2
make[1]: Leaving directory
make: *** [all] Error 2

I cannot for the life of me figure out why this is not working as I have
reverted to a setup with no changes over what was working a day ago.  I am
at a loss for what to do, and was hoping I could get some guidance on
correcting whatever my bug is.

Many thanks,
Griffin Wright
