The simple answer is probably to select unix-jthreads
when configuring :-)

For what it's worth, here's the configure line I use to compile
from x86 Debian 3.0 to powerpc linux:

set -e; cd ppc750; CC=/opt/hardhat/devkit/ppc/7xx/bin/powerpc-linux-gcc CFLAGS="-mcpu=750
-D__PPC750__" LD=/opt/hardhat/devkit/ppc/7xx/bin/powerpc-linux-ld
KAFFEH=/home/dank/wk/ixos/dap/ppc750-release/build/bin/kaffeh ac_cv_alignmentof_voidp=4
ac_cv_long_division_broken=yes ac_cv_long_long_modulo_broken=no ac_cv_long_modulo_broken=yes
ac_cv_strtod_m0_broken=no kaffe_cv_signal_one_shot=no ../kaffe-1.0.7-libtool1.4e/configure
--without-x --build=i686-pc-linux-gnu --host=ppc-unknown-linux --prefix=/opt/kaffe \
--with-threads=unix-pthreads \
--disable-debug \
--disable-xprofiling \
--disable-xdebugging \
--disable-feedback \
--without-profiling \
--without-stats \

Configure prints

checking for pthread_create in -lpthread... yes

It creates a top-level Makefile containing

VM_LIBS = -lpthread

and my link lines do indeed include

If this isn't happening for you, something's wrong...

You have a newer version of the source than I do,
but I suspect it ought to work similarly...
