Thanks for your testcase. I am able to create a small testcase based
on yours. The current Linux linker, 2.11.92.0.10, will detect the
loop:

# make
cc -g -O -fPIC   -c -o foo1.o foo1.c
cc -shared -o libfoo1.so foo1.o -Wl,--version-script,libfoo1.map 
cc -g -O -fPIC   -c -o foo2.o foo2.c
cc -shared -o libfoo2.so foo2.o -Wl,--version-script,libfoo2.map 
cc -g -O -fPIC   -c -o bar.o bar.c
cc -nostartfiles -nostdlib -shared -o libbar.so bar.o libfoo1.so libfoo2.so
/usr/bin/ld: libfoo2.so: indirect symbol `foo' to `foo@@ver1' is a loop
libfoo2.so: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

But on the other hand, I think it is a linker bug. I am looking into
it now.
