abi_check build broken

[Andreas Jaeger]

With current CVS, abi_check does not build anymore (on both
i686-linux-gnu and x86_64-linux-gnu):

/builds/gcc/misc/gcc/g++ -shared-libgcc -B/builds/gcc/misc/gcc/ -nostdinc++ -B/opt/gcc/3.4-devel/i686-suse-linux-gnu/bin/ -B/opt/gcc/3.4-devel/i686-suse-linux-gnu/lib/ -isystem /opt/gcc/3.4-devel/i686-suse-linux-gnu/include -isystem /opt/gcc/3.4-devel/i686-suse-linux-gnu/sys-include -include bits/stdc++.h -g -O2 -D_GNU_SOURCE -o abi_check abi_check.o  -L/builds/gcc/misc/i686-suse-linux-gnu/libstdc++-v3/src -L/builds/gcc/misc/i686-suse-linux-gnu/libstdc++-v3/src/.libs -lm

make[4]: *** [abi_check] Error 1

Why is -lpthread not added anymore?

I configured with:
/cvs/gcc/configure  --prefix=/opt/gcc/3.4-devel --disable-nls --enable-threads=posix --enable-clocale=gnu --enable-__cxa_atexit --enable-shared --enable-languages=c,c++,ada,treelang,java,f77,objc --with-system-zlib i686-suse-linux-gnu --with-gcc-version-trigger=/cvs/gcc/gcc/version.c
