As you can notice, there's no "-lpthread" in any of above commands.
So, you may workaround this by adding -lpthread also to LDFLAGS, or
simply doing it by hand whenever such thing occurs, eg. using
something like:

cc -g -I/home/carl/garnome/include -I/usr/X11R6/include
-I/usr/local/include -O2 -pipe -o .libs/name-client-2 name-client.o
name-support.o  -L/home/carl/garnome/lib -L/usr/X11R6/lib -L/usr/local/lib
-L/usr/compat/linux/lib -lpthread -L/usr/lib
../../../src/orb/.libs/libORBit-2.so ./.libs/libORBitCosNaming-2.so

(for this particular case, I've just copied the command verbatim, and
added -lpthread after -L/usr/compat/linux/lib)

I didn't try this, but I hope it will help.

Cheers,
