I've now checked the LinuxThreads and NPTL configurations for
arm-none-linux-gnu; along with the patch I just checked in, they're
fine too.  ARM is in pretty good shape.

arm-none-linux-gnu looks fine.  arm-none-linux-gnueabi is irrelevant,
since everything is GLIBC_2.4.

For the record here's some scripts I found handy for comparing ABI
lists.  Run the first one to generate an abilist and merge it with
the existing ones into the current directory; run the second one
to compare a new library to that.  I used this to build baselines
from Debian since I did not have an FSF ARM 2.3 build available.

glibc-abilist.sh:
#!/bin/sh

srcdir=$1
library=$2
config=$3
cross=$4

set -e

base=`basename ${library} | sed 's/\.so.*//'`
${cross}objdump --dynamic-syms ${library} > ${base}.dynsym
LC_ALL=C awk -f ${srcdir}/scripts/abilist.awk \
	${base}.dynsym > ${base}.symlist
LC_ALL=C awk -v config=${config} -f ${srcdir}/scripts/merge-abilist.awk \
	${srcdir}/abilist/${base}.abilist ${base}.symlist \
	> ${base}.abilist


glibc-check.sh:
#!/bin/sh

srcdir=$1
library=$2
config=$3
cross=$4

set -e

base=`basename ${library} | sed 's/\.so.*//'`

#abilist=${srcdir}/abilist/${base}.abilist
abilist=${base}.abilist

${cross}objdump --dynamic-syms ${library} > ${base}.dynsym
LC_ALL=C awk -f ${srcdir}/scripts/abilist.awk \
	${base}.dynsym > ${base}.symlist
LC_ALL=C awk -v config=${config} -f ${srcdir}/scripts/extract-abilist.awk \
	${abilist} \
	| diff -p -U 0 - ${base}.symlist
