This appears to be an artifact of the use of the host compiler to
bootstrap the linux headers into the glibc build procedure.  I worked
around it in the patch that I posted by arranging for -D__ARM_EABI__
to be tacked onto the host compiler during that pass.  This satisfies
glibc 2.4's demand for the EABI-style syscall base.

Steve, if you would care to try the patch that I posted, I would be
interested to know whether it works for you.  It contains all of the
patches that I know of applicable to the latest binutils and to NPTL
in glibc 2.4.  (Adjust the target and cpu optimization in earm.dat and
replace earm.config with your kernel config before running
./latest.sh.)  You should get a full EABI soft-float NPTL/TLS
toolchain; you should then be able to configure and build the
2.6.16.11 kernel unpacked under the build directory.

Cheers,
- Michael
