CMake IA64 FPIC problem

bar.c:

 int i = 0;
 void bar()
  {
  i = 5;
  }

foo.c:

 extern void bar();
 void foo()
   {
   bar();
   }

Compiled with

 rm -f libbar.a *.o
 gcc -c bar.c
 ar cr libbar.a bar.o
 gcc -c foo.c
 gcc -shared -o libfoo.so foo.o -L. -lbar

Will fail:

 /usr/bin/ld: bar.o: @gprel relocation against dynamic symbol i collect2: ld returned 1 exit status

But, putting:

 gcc -fPIC -c bar.c

works.
