Many thanks for your answer. With you parameter and a new one, I build the
toolchain successfully. I used following parameters:

TARBALLS_DIR=/usr/local/src/mips-toolchain/downloads
RESULT_TOP=/usr/Applications/tc-mips-newlib1.13-bu2.15-gcc3.4.3
GCC_LANGUAGES="c,c++"
TARGET=mips
TARGET_CFLAGS="-O2 -finline-limit=10000"
BINUTILS_DIR=binutils-2.15
BINUTILS_URL=ftp://ftp.gnu.org/pub/gnu/binutils
GCC_DIR=gcc-3.4.3
GCC_EXTRA_CONFIG="--with-gnu-as --with-gnu-ld --disable-multilib
--with-newlib"
NEWLIB_DIR=newlib-1.13.0
NEWLIB_URL=ftp://sources.redhat.com/pub/newlib

Apparently, from below post, option --with-newlib is needed in
GCC_EXTRA_CONFIG for gcc 3.4 (as suggested by Steve, I have googled a bit
more than previously).
http://gcc.gnu.org/ml/gcc/2005-01/msg00192.html

In fact, I'm wondering why --with-newlib is not set for the second phase of
gcc build in crosstool-0.32/contrib/newlib/crosstool-newlib.sh.

There is also a non fatal error at the end of crosstool-newlib.sh:
/usr/local/src/mips-toolchain/crosstool-0.32/contrib/newlib/crosstool-newlib
.sh: line 166: syntax error near unexpected token `esac'

Apparently, there is an old esac than has not been erased.

However, I do not claim the produced chain is working. We still have issues
with that. :(

Yours,
david
